So today I was with my I guess 9-10yo cousin. He was playing clash of clans.
I told him, “you can also make this type of games”.
After this he was stared at me for like 25-30sec his face expression was awesome. Then said “seriously? I thought games are developed on a certain place where all the games are made.”
I said “no anyone can create games if you know how to code and all.”
After that multiple questions was on the way and I answered all for him.
But he totally amazed with this knowledge. And I felt good to.10 -
Interviewed a dev for a junior role earlier this week...my first question:
const numbers = [0.1, 0.2, 0.3];
let sum = 0;
for (i = 0; i < numbers.length; ++i) {
setTimeout(() => {
sum += numbers[i];
}, 0);
}
// Refactor the preceding code so that the following returns true.
console.log(sum === 0.6);
---
He had no idea where to even start, so I asked him to walk through the code with me line by line, he couldn't get past line 1 - literally didn't know what an array was... I walked through the code with him and he just started to look more and more lost.
I didn't even bother with the rest of my questions on OOP, FP, etc...
Am I really expecting too much of somebody that claims to have 2 years practical experience in JavaScript, jQuery, Angular, and PHP?
Do you think this is a problem a junior dev should be able to solve...even if it takes some hand-holding?57 -

It's so fuckin hard to work with people who don't get sarcasm or humour.

Oh you'll love this. A master password to access any user.
Something like:
const masterpassword = <dayABCyearXYZ>
if (password == dbpassword || password == masterpassword) { // allow access }
The best part is this code is available to our clients. They can literally see how this "master password" is generated. And they don't want me to remove it because it's being used by testers.7 -

On my first week in the internship, I have to create a small website and it has to be finished ASAP. So I used Bootstrap.
After finishing I tested the website in chrome debugger tools for every screen size (design responsiveness), it was working fine. My stupidity was that I haven't tested on actual mobile/tablet.
The site was live, I send the link to one of my friends and he said "why everything is so small? looks like I'm browsing on PC". I quickly grab my phone and visited the site and it was not responsive on mobile. Started to check the code again, tested again on chrome tools it was working. But not on mobile. Changed the bootstrap file but no fucking changes on mobile.
After few moments of thinking, I realized that I haven't included the "meta viewport" tag. I felt so stupid and it was kind of embarrassing for me.
Now I first include meta tags before working on new project.5 -

I am currently in a bit of a (well-deserved) lull at work, both of my projects are finishing up/ finished, so tomorrow should be pretty light, as the latter half of today was.
And I have really gotten interested in the HTTP protocol. It's so interesting learning how it all works under the hood.
So I think I'm going to be researching/ messing around with creating a cpp project that essentially implements cURL from the ground up, creating sockets, reading from them, parsing the HTTP requests... all that. I don't expect to actually get it done, but it should be an immense learning experience. I have a clear goal: implement this function:
std::string get(const std::string&);
Once I'm able to just GET as simple as that, I know I have achieved my goal!3 -

If you are teaching a newbie HTML and basic JS using ES6/ES2015 features, the "Hello World" app probably would be:
<!-- index.html -->
<html>
<body>
<div id='container'>
<h2> Enter a Name and Hit The Button</h2>
<input id='name'>
<button id='change-name'>Say Hello</button>
<h3 id='name-display'></h3>
</div>
<script type='module' src="./index.js"></script>
</body>
</html>
//index.js
import {sayHello} from './hello.js';
let displayArea = document.getElementById('name-display');
let input = document.getElementById('name');
let button = document.getElementById('change-name');
button.addEventListener('click', () => {
//displayArea.innerHTML = "Hello World"
displayArea.innerHTML = sayHello(input.value);
});
//hello.js
export const sayHello = (name='World') => {
return `Hello ${name}`;

So met a guy today in college and it was his first day in class. He told me that he is working as software engineer and having 4 years of experience and primarily works with Java lang.
We do programs in Java for practicals and I'm not good with Java (I fuckin hate). I thought maybe I can ask for help from this guy if I'm stuck. And so the practicals started.
And guess what the guy did not know how to compile Java program on 'cmd' and was seeking help from other guy. I'm like what the actual fuck. How the fuck he has 4 years of experience and can't compile a program. Can't even able to set path. Total idiot. Fuck this shit.10 -

TL;DR Pluralsight should be ashamed for taking 299 USD a year and writing some very low-quality quizzes.
I've always heard that Pluralsight is a great platform having some high quality courses, so I chose it as a benefit, as our company was giving us some budget for learning purposes. I've paid (or rather the company did it in the end) 299 USD for this year, which, I guess is not much for US standards, but it is a lot for Eastern European standards.
I didn't actually get to the point of watching any of the courses, but I started to use a feature called "Stack up", which is a long series of questions in a specific theme, like Java, Kotlin, C++, etc., accessible once a day. I must say, I'm amazed by the fact, that people pay quite a great amount of money and they get something so poorly made with a lot of errors and stupid questions.
Take the question from the included image for example. Not only that the 2 possible answers are repeated (and thus I failed to select the correct one from 2 equal answers), but the supposedly correct answer is also missing some type specifications. No Java compiler will compile it this way as far as I know. There would be at least 3 ways to fix it.
Then there is today's gem (should be included as first comment) as well, where the answer is wrong in both Chrome 96, Firefox 95 and Node v10. Heck, THIS IS one of the reasons why you should never use `var` in your JavaScript code, but always `let` and `const`!
So the courses on Pluralsight might be good, but I would be ashamed, if I were to release something like this. People might actually try to solidify their knowledge by solving these quizzes but instead of learning something useful, they will be left with some bullshit. I just don't get how could they release a feature with so much incorrect information and I am kind of disappointed, even if I didn't try the courses yet.

LOL that's why I love C!
The function pointer cast for strcmp because qsort expects a compare function with two const void * pointers instead of two const char * pointers, that's just beautiful.
Not to mention the hack to abuse strcmp on a struct - which just works because the first struct member is a string and the rest just gets swapped with memcpy as opaque data.
I guess that wouldn't pass a code review at work. :-)

Project in college, many moons ago.
Team is building a robot for a project. Nothing too crazy, it does some simple tasks like walk along a path and shit.
3 weeks for the project. 3 team members.
The largest graded part of the project is the ability to follow a path based on vision.
The 3rd member INSISTS on doing that part, he says “I want to prove to the professor that I am the smartest in the class so he helps me get a work term.”
Of course, my other partner and I see this as the complete selfishness of a child who will never be employed anywhere worth talking about anyways. He is a big asshole about it and we end up giving in.
## Week 1
We get our parts done (working together the way a team would) without his help.
He struggles, hits walls, complains. You know, dumbass grown child stuff...
## Week 2
We offer to help since we are done. He refuses. The teacher sees all of this and doesn’t like it at all.
After class the 2 of us go to the teacher and let him in on the details. The guy insisted, he is struggling and will not take help etc.
Teacher goes and talks to him and tells him it is a team project for a reason and that we should be helping. He says yes.
Then he misses the rest of the classes that week and send an email saying...
“Since everyone decided to keep interrupting me and breaking my train of thought, I could not get anything done in class. Therefore I will be staying home to finish the project from there.”
And to top it off, he didn’t even take home the robot’s connectors he needed to do the damn thing. Haha.
## Week 3
We know he wasn’t going to get it done, so we approached the teacher. We make it clear that we have done all we can and that we are not ok with losing marks because of this.
Since we are both good students that he likes, he decides to give us an option.
You can take a 50% on his part even if he doesn’t get it done (for trying to help) or we can do it ourselves and he won’t get the marks if he doesn’t finish.
## Night before
We say fuck it and do the thing.
In fact, since we were learning Java at the time we decided to do it in Java. Our other prof sees us playing with robots and gets excited, he stays with us and suggest improvements.
In the end we rewrite all 3 robot functionalities in Java and hand in the project the next day.
## The day of
Partner 3 comes into class and says this...
“That walking path part is impossible, I didn’t get it done, but I bet nobody else did either. So at least we will get a 60% on the other 2 parts!” (With a big shit eating grin)
Prof calls our group up. We walk up and the prof looks at the 3rd guy and says.
“Since you have decided to do your part alone, we will have you present your part alone at the end of the groups”
He tries to say something but the prof cuts him off and tells him to sit down.
We show all of our code and the robot does everything perfectly.
Groups go by, now it’s that guys turn.
He says that the walking part was impossible but seems to realize right away that he just saw EVERY other group get it working.
The teacher ask him to stay after class.
## Result
We got a 98 (prof said he was hoping we would have done in VB like asked but he liked the result a lot).
Other guy gets a 5% for his non-working spaghetti code on 0s on the other 2 sections. He blames us, of course.
Bonus Content:
That same asshat above once said this to me...
“I don’t indent my code so that if I work for a company and no one else can understand the code then I am unfireable!”
Yes, he wrote all code like this...
const Example = () => {
Stuff
More stuff
For() {
Stuff
If() {
Stuff
}
}
}
Fuck that guy🖕🏽3 -

You know what really grinds my gears? When people criticize a programming language but uses edge cases and stuff that can be avoided by using the tried and true "don't be an idiot". Take for instance JavaScript, a language I like and a language that has a lot you can criticize. But I feel like a lot of peoples criticism isn't warranted.
What's that? No ints? Use parseInt or Math.floor.
What are you saying? == works in strange ways? Yes, that's what we have === for.
Type coercion is wonky? Think it's weird how string + int works differently than string - int? Wanna string with number + - + - - + - - etc? Don't! Don't add strings and ints, don't subtract strings and ints. You can't in statically typed languages and you aren't supposed to in dynamically typed
Adding arrays and objects, arrays and arrays, objects and objects etc. is inconsistent? Why are you trying to do that?
Adding floats together gives odd results? Now we're getting somewhere! And Mozilla responded to that with a method called toFixed.
Declaring variables with var doesn't always work that well? Use let and const
Then there's this weird attitude that some people I've met have, where they will complain about the module system and how "well you rely on the community for those packages" as if it's a bad thing. And then coming with the "well you don't know what the (open source) packages do internally" as if I (for the most part) give a shit. Then they'll swear by companies like Zend or Microsoft as if they can't just stop supporting the languages they use. Maybe it's just because I like community content more because of video game mods.
Wanna criticize JS, then there's plenty to talk about. Like the built in date object is basically shit. Or how in NodeJS you can have node_modules in your node_modules. Or how classes don't really have the best syntax. Left-Pad. And so on (it's too late for me to be able to remember much more).1 -

Do you guys drop the S from your variable names? I am constantly in a dilemma as to what makes more sense.
For example a SQL Table:
Books
----------
BookID
BookName
....
---------
OR
Book
---------
BookID
BookName
.....
---------
Or even in a language like C# or JavaScript:
const BOOKS
var books
let books
or
const BOOK
var book
let book
Even if you have multiple items in that variable/table it seems very redundant to ever have the s.
What do you guys think? Any input appreciated!
Happy coding!24 -
this happened two months before,
there's a UI designer guy at my office when I was about to leave the office he gave me a web page UI which has to be done by the next day.
Next day I started working on that page when I was halfway done he came to my desk and said: "there're some changes in design, the client doesn't like this part and this."
I'm like, why the fuck you didn't take client confirmation on the first place that's a fucking basic and first thing need to do. Just like the client you are a fuckin idiot. And now we don't hang out anymore. -
How about creating a new programming language named "C slang"
highlights from the language:
1. variable declaration :
by default, all declaration are var, but inorder
to declare a constant, write:
cunt a = 15; // means const a = 15;
2. input and output :
suck(b) // input stored in variable b
spit(b) // output b
3. function declaration:
f**k <function_name>(parameters);
4. null or None will be replaced by sh*t
for example: if(node root == sh*t)....
any other sh**y recommendation will be appreciable6 -

for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array)

Fuck you Javascript17 -
I want to explain to people like ostream (aka aviophille) why JS is a crap language. Because they apparently don't know (lol).
First I want to say that JS is fine for small things like gluing some parts togeter. Like, you know, the exact thing it was intended for when it was invented: scripting.
So why is it bad as a programming language for whole apps or projects?
No type checks (dynamic typing). This is typical for scripting languages and not neccesarily bad for such a language but it's certainly bad for a programming language.
"truthy" everything. It's bad for readability and it's dangerous because you can accidentaly make unwanted behavior.
The existence of == and ===. The rule for many real life JS projects is to always use === to be more safe.
In general: The correct thing should be the default thing. JS violates that.
Automatic semicolon insertion can cause funny surprises.
If semicolons aren't truly optional, then they should not be allowed to be omitted.
No enums. Do I need to say more?
No generics (of course, lol).
Fucked up implicit type conversions that violate the principle of least surprise (you know those from all the memes).
No integer data types (only floating point). BigInt obviously doesn't count.
No value types and no real concept for immutability. "Const" doesn't count because it only makes the reference immutale (see lack of value types). "Freeze" doesn't count since it's a runtime enforcement and therefore pretty useless.
No algebraic types. That one can be forgiven though, because it's only common in the most modern languages.
The need for null AND undefined.
No concept of non-nullability (values that can not be null).
JS embraces the "fail silently" approach, which means that many bugs remain unnoticed and will be a PITA to find and debug.
Some of the problems can and have been adressed with TypeScript, but most of them are unfixable because it would break backward compatibility.
So JS is truly rotten at the core and can not be fixed in principle.
That doesn't mean that I also hate JS devs. I pity your poor souls for having to deal with this abomination of a language.
It's likely that I fogot to mention many other problems with JS, so feel free to extend the list in the comments :)

const abc: string = 'Hi';
Can we take a moment to appreciate how retarded it is that TSlint throws a warning here that the string type is inferred and unnecessary.
I want to put the type there because it looks more readable. Code looks better if every variable has a type, irrespective of whether it's a constant. I know the fucking type is inferred you braggart linter bitch. What the fuck does it expect? A fucking award because it inferred that a string constant is of the fucking type string? How the ever loving fuck does that warrant a squiggly ass yellow warning line, reminiscent of that smartass 10 year old in class who has to yell out every answer when the teacher never asked a question.5 -

I am in a situation where I am tired to give suggestions or implement any improvements to the company's app. I am in a situation where I will just do as told, nothing more, nothing less.
Regardless of how many suggestions or improvements I had made, the boss is constantly sceptically asking for "BLACK AND WHITE " proof. Sometimes, something does not require proof but cause and effect. As the application constantly prompts a DataType issue, which is a common bug in this app! I declare datatype the issue went away.
I wonder how this application can go further when they declare every variable as `var`, not using `const` for constant value, and redundant methods everywhere, most methods are not specific (in dart when you do not specify the method, the method become `dynamic`), a long list of nested if-else for something can be easily solved with switch case, etc.
So, today, right now, I will revert every improvement, and keep the original structure. If anything goes wrong, I know why it happens (deep down I will say "I told you so"). I am here to work for food, not to reinvent the wheel.
I'm so exhausted to the point where I will just go along and tell my co-worker "as you wish"
No more me suggesting.
No more me giving ideas.
No more me pointing the mistakes .
I will let them find out themselves is much better than I say it, just to prevent getting unnecessary hatred from them.
The best punishment to give somebody is to never mention their mistake let their ego do the job of consuming them into ignorance and asleep, and never wake them up. Let them commit the same mistakes repetitively until them realised there's no way to revert.5 -

AndroidOS.
Why: well it's built on Linux kernel so first good thing.
Due to open source everyone can get cheap (under $50) smartphones running on Android with millions of app to access. We can create custom ROMs.

typeof rant === "Encouragement"
Never let your self down, try to be your own const in life that know his scope and traits well enough to construct a peacefull life without any uncatched exceptions. Also try to return something to the public, keeping your magic pointers to your private makes it hard to review your glorious source of thoughts. And if it is getting hard try to REST a bit and git some timeout.

Any JavaScript developers out there willing to help me out with something?
I have an interview question that I like to ask candidates that no one ever seems to get right. But, to me, it seems pretty basic, so I expect MOST JavaScript developers at almost any level of expertise to get it, and I like it generally because it demonstrates some core knowledge of JavaScript concepts and syntax.
But I want to verify that my feelings about it are reasonable, because give how few ever seem to get it right (and I'm talking across literally hundreds of interviews, MAYBE 2 people have ever gotten it right), I'm starting to wonder if I'm right or not.
Look at this code, and then answer the question after. Please do so off the top of your head and without testing anything since that's normally the experience a candidate would have. I'll give the answer after some time for anyone who gets it wrong but is curious.
But this isn't about YOU getting it right or not, and it's not about whether it's the best way to do something in JavaScript or anything like that, it's just about whether it's a reasonable question and whether my expectation that MOST JavaScript developers should get it right is fair.
const O = {
sayHello : function() { alert("Hello"); }
};
const S = "sayHello";
Question: using ONLY the variables O and S (and you MUST use both), write code that executes the sayHello function.

Why React is soo complicated? Seriously why do we always need to use some stupid shit like this

I was once a pure server side developer. Then came full stack development. So in order to keep up with the competition, I had to brave through front-end development.
But goddamn javascript, make up your mind between functions, and “Objects”.
Also variable visibility. Goddamnit. I thought ES6 was widely supported. I was happy doing const and let bbut goddamn testing frameworks, grunt and shit. Can’t make up it’s mind to support it unitedly.
And lastly, IE. Goddamn it, why the fuck are you not supporting Promise by default. We’re fucking 2017. [insert slowpoke meme]

Wasted a day as Shitlock Holmes with the build chain.
It would not reproduce the firmware hexfile that had been checked in. Reverse engineering that along with the mapfile to find out the cause, it was a const string that was guarded by an ifdef from another file that was auto-generated as prebuild step via a script that fetched some version control info.
Or, it would have been if the installation instructions had been correct and someone had described that no spaces in the absolute path name of the project are allowed. Otherwise, that shit just failed silently.
I then had to reverse engineer the intended workflow from the commit history in the version control to figure out that the last dev obviously hadn't quite understood the project specific workflow and how the version control interacts with these build scripts.
At least, I finally did get a matching hexfile.1 -

Oh... Interesting. Bukkake princess survived and even spilled the tea.
Someone was trying to be overly "eager" to avoid magic numbers...
They concatenated a header name out of several const vars which stem from a static class with like... 300? 400? vars of which I can make no fucking sense at all.
Class literally looks like the most braindamaged thing one could imagine.
And yes... Coming back to the network error I'm debugging since 2 days as it is occuring at erratic intervals and noone knew of course why...
One of the devs changed the const value of one of the variables to have UTF 8 characters. For "cleaner meaning".
Sometimes I just want to electrocute people ...
The reason this didn't pop up all the time was because the test system triggered one call with the header - whenever said dev pushed changes...
And yeah. Test failures can be ignored.
Why bother? Just continue meddling in shit.
I'm glad for the dev that I'm in home office... :@
TLDR: Dev changed const value without thinking, ignoring test failures and I had the fun of debunking for 2 days a mysterious HAProxy failure due to HTTP header validation... -

so I started a side project a while ago.
the only thing it could do was to create some files with desired names and extensions. so this was basically a pretty simple editor.
I left this project with no future plans for a month or so until I started working on it again this week. I added comments to the editor, a console user interface.
the ui isn't futuristic. the program runs in the console. it just lists all the files and folders where the program is currently located in. in the beginning it could take user input and that input was the location where the files created in the editor would be saved. then I thought: it would be more interesting if I created a folder in which I saved the files from the editor. so I did this thing.
then I thought, again: hey, this console is pretty boring and stuff. why should I add some special commands? and so I did.
now you can create an empty folder, before you created a folder and saved at the same time the files created in the editor. now you can open another folder in which you can do the same stuff as before. you can get the current location of the folder you are currently in, so you don't get lost in your fancy computer. you can delete a folder completely, set color, reset color.
but one thing that I lost almost ONE FREAKING HOUR ON IT TO MAKE THE USER EXPERIENCE BETTER was the following: when creating a folder, either empty or with the files from the editor, the program automatically opens the folder, not in the console(hey, I didn't thought of that) but in the file explorer from the os. now it only works for windows and windows explorer because I used system(const char*). I know it's not portable or efficient but I just wanted things to work, I will optimise it later.
the thing that made me lose that one hour debugging was figuring out how to open that file.
ok, so I used windows api with GetCurrentDirectory, I knew how to use system, I knew how to form the path that would match up with the folder, I almost knew how to open the folder with system().
the problem was that I had the path complete, but if the folder had white spaces system() wouldn't recognise the freaking command!
so the string with the path would also contain the command used in system() and I would just .c_str() the string so it could work. as an example my wrong way to make the path was this:
"start C:\\path"
can you figure out what is the problem?
you don't?
it's just so trivial.
how cannot you figure it out?
of course you NEED to put "explorer" between the start command and the actual path!
pffft, you idiot! so easy to figure it out.
so yeah, the right way to open a folder is like this:
"start explorer C:\\path to heLL!!"
p.s.: I still don't understand why putting explorer works and without it doesn't. without explorer it just just says that path with the first word before the white space doesn't exist. -

1. Find a function: getDayDiff(d1, d2)
2. d1 and d2 are momentjs dates.
3. See that function performs complex ancient math rituals and then returns an integer
4. Try to rewrite function, return d2.diff(d1, 'days')
5. Should be OK right? Run tests
6. Whole module melts down. WTF?!
Turns out the math performed returned the difference + 1 because it included the current day which moment's diff() function does not (out of the box).
Processes that depended on this function then uses the result like this:
const diff = getDayDiff(d1, d2)
if (diff-1 == should_match) { /* more fun logic */ }

So I figure since I straight up don't care about the Ada community anymore, and my programming focus is languages and language tooling, I'd rant a bit about some stupid things the language did. Necessary disclaimer though, I still really like the language, I just take issue with defense of things that are straight up bad. Just admit at the time it was good, but in hindsight it wasn't. That's okay.
For the many of you unfamiliar, Ada is a high security / mission critical focused language designed in the 80's. So you'd expect it to be pretty damn resilient.
Inheritance is implemented through "tagged records" rather than contained in classes, but dispatching basically works as you'd expect. Only problem is, there's no sealing of these types. So you, always, have to design everything with the assumption that someone can inherit from your type and manipulate it. There's also limited accessibility modifiers and it's not granular, so if you inherit from the type you have access to _everything_ as if they were all protected/friend.
Switch/case statements are only checked that all valid values are handled. Read that carefully. All _valid_ values are handled. You don't need a "default" (what Ada calls "when others" ). Unchecked conversions, view overlays, deserialization, and more can introduce invalid values. The default case is meant to handle this, but Ada just goes "nah you're good bro, you handled everything you said would be passed to me".
Like I alluded to earlier, there's limited accessibility modifiers. It uses sections, which is fine, but not my preference. But it also only has three options and it's bizarre. One is publicly in the specification, just like "public" normally. One is in the "private" part of the specification, but this is actually just "protected/friend". And one is in the implementation, which is the actual" private". Now Ada doesn't use classes, so the accessibility blocks are in the package (namespace). So guess what? Everything in your type has exactly the same visibility! Better hope people don't modify things you wanted to keep hidden.
That brings me to another bad decision. There is no "read-only" protection. Granted this is only a compiler check and can be bypassed, but it still helps prevent a lot of errors. There is const and it works well, better than in most languages I feel. But if you want a field within a record to not be changeable? Yeah too bad.
And if you think properties could fix this? Yeah no. Transparent functions that do validation on superficial fields? Nah.
The community loves to praise the language for being highly resilient and "for serious engineers", but oh my god. These are awful decisions.
Now again there's a lot of reasons why I still like the language, but holy shit does it scare me when I see things like an auto maker switching over to it.
The leading Ada compiler is literally the buggiest compiler I've ever used in my life. The leading Ada IDE is literally the buggiest IDE I've ever used in my life. And they are written in Ada.
Side note: good resilient systems are a byproduct of knowledge, diligence, and discipline, not the tool you used. -
So I have this code written in node:
Function connect(){
const client = net.blahblah
client.on('close', () => {
Connect()
}
}
As the connect is called from within the close call back, it wouldn't be recursive right? Like if it disconnected a million times, it shouldn't throw a recursion error or use up a bunch of memory right? Or am I thinking about it wrong?2 -
I just reviewed a pull request with a test case like (pseudo code):
# Test MyService
const mock = createMock(myService.myMethod)
.whenCalledWith("foo")
.returns("bar");
assert(mock.myMethod("foo") === "bar"));
Why though? Why are we testing the mock? What is happening here? This test has no reason of being there instead of a fuzzy feeling that we now have unit test to lure us into a false sense of security.
I asked why we don't do an integration test. Response was: "They are slow."
Well, duh, but at least they would actually test something.
What do you gain by asserting that the mock is working the way you set it up?3 -

Cool project, cool people, but everything-just-works™ code makes it hard.

Note: I have deleted my previous version of this question as I found it lacking crucial information and therefore being prone to misunderstandings.
Question : In C/C++ you can position the keyword 'const' either left or right of the left-most type specifier. Which variant do you prefer?
I ask that because I'd like to hear your opinion. Although I have been working with C over three decades now, I only learned this a couple of years ago. After some experimentation I decided for myself, that I like the placement to the right more. Although the positioning to the left is taught in literally every book and course, the original placement suits me better.
One reason, of many, is the listing of many member variables in structs or classes. To have them nicely aligned, I always had to put 'const' either on the previous line or put in extra indention to everything non-const. That was quite irritating sometimes.
Another, and my main reason is, that when reading from right to left, the rhs variant just makes more sense than the lhs variant. Reading from left to right almost never makes much sense without straining your eyes. But that is, of course, highly subjective.
This is even more so if you have pointers. The 'const' keyword modifies the type identifier(s) to the left. So if the 'const' is (anywhere) left of the '*', the data is const. If the 'const' is right of the '*', the pointer address itself is const. The same applies to references.
Examples, read right-to-left:
int* const i; // i is a const pointer to int data
int const* i; // i is a pointer to const int data
int const* const obj; // i is a const pointer to const int data
The "classical" or "taught" way, that is found almost everywhere would read, still right-to-left:
int* const i; // i is a const pointer to int data
const int* i; // i is a pointer to int data const
const int* const obj; // i is a const pointer to int data const
Not only that the second "lhs" form reads worse, it also looks worse. In my opinion, the first "rhs" variant makes it simpler to quickly determine that we are dealing with three ints, while on the second "lhs" variant, one has to first get past the 'const' keywords.
I know that this is not only a matter of taste, but of course of agreement, too. You can not just go and switch the 'const' placement in long standing projects. That would surely piss of a lot of people. Or even cost you your job.
But I like to know what you people think and why.
Thanks a lot in advance!5 -

or i get sid the it kid, who gives non ironic lessons in fucking PHP 😂😂😂😂 in 2024 on youtube, and yet acts like he's a badass because he pointed out a 'redundant' 'const' in my code 😂😂😂😂 actually i don't know why in the first place i listened to any of it... going my own way has ALWAYS been the best way
by 2030 i will sell my saas(es) for 500k(+) and wonder why i even gave clowns on this platform the time of day
you know what? fuck it, it's been fun devrant, as of today i become a hermit, sick of this planet, and these apes
read books, go running, learn math (or any skill at that matter) and stay calm.
i can't describe in words to all of you how much a fucking abysmal waste it all is... just build useful stuff that helps people. the enormous (and trust me, it is absolutely eclipsingly enormous) discussion about everything around everything else is truly and utterly mind numbing and time wasting to the absolute core

Lol. In the years that `const` and `let` have been in Javascript, not once have they ever helped me read the code better or caught a bug. They have not helped me understand anyone else's code, nor have they really helped convey any sort of meaning for other developers that I have heard.
Usually the rule is, const first, then change it to let if you need to. It adds nothing.
All this gold plating is weighing things down.15 -

Looking into Kotlin, and it seems pretty cool, but I just can't get over how unnatural and annoying the mapOf syntax is.
In JavaScript: const obj = { a: 1, b: { c: 3, d: 4 } }
In Kotlin: val obj = mapOf("a" to 1, "b" to mapOf("c" to 3, "d" to 4))5 -
It's been one month since I joined devRant, the community is awesome and it is good to be here.
It was the second-best suggestion given by Google in recent times. -
Am I the only one who wants to be able to write functions in a human readable way, allowing for parameter in-between the words?
Instead of defining:
const enforceStringEndsWithChar(string: string, char: string) => {...}
I want to define it as:
const enforce(str: string)EndsWith(char: string) => {...}
.
.
.
I'll see myself out.6 -
Quick JS tip
If you want to split a string into characters, you can use the ES6 spread operator
If you have
const name = 'react-dev'
You can just spread it like this:
const charsInName = [...name]5 -
True story:
While doing a CR stumbeled upon the following line, with no documentation attached:
CONST = "{0}{1}{3}//{4}{5}{6}//{7}.{8}" -
I’m so sorry if this is the place for questions. I’m terrified of stack overflow and have been searching for a week for a solution and can’t find one. This is for React.js people.
I was tasked to create a webpage with react. The limitation is, they did not wanna adopt the node.js dependency. I said ok, I’ll figure it out. You can inject react, material UI, and babel with script tags in HTML, then put ur lil components in it. I did that and it works beautifully.
However, now I have to write tests for this. I think it’s actually impossible without a way to render React, so I have to use the browser, or node, right? I convinced my boss to allow me to use a node.js container just for testing, which I thought would make my life easier.
I don’t know how to render this thing with node. It’s just an HTML file that pulls react via script tags, and idk how to serve html with node. Additionally, none of the React testing libraries seem to support testing a system that wasn’t designed to be served with node, at least not easily. My gut tells me that the complication with how things are imported contributes at least a little to this (dependencies pulled via script tags in the HTML file and made available to react through global const variables).
I could be wrong about any of this — im fairly new. But how tf do I go about testing these react components? For reference, if you go to Reacts docs, there’s a section called “add react to a page in one minute” that’s pretty much what I did.20 -
It's time for war!
I have two examples doing the same thing. They're bot generated by chatGPT.
React:
import React, { useState } from 'react';
function IncrementalButton() {
// Create state to hold the count value
const [count, setCount] = useState(0);
// Function to handle incrementing the count
const increment = () => {
setCount(count + 1);
};
return (
<div>
<h2>Count: {count}</h2>
<button onClick={increment}>Increment</button>
</div>
);
}
export default IncrementalButton;
VUE:
<template>
<div>
<h2>Count: {{ count }}</h2>
<button @click="increment">Increment</button>
</div>
</template>
<script>
export default {
data() {
return {
count: 0,
};
},
methods: {
increment() {
this.count++;
},
},
};
</script>

So I thought I had a basic, high level understanding of C++ STL strings, pointers, copy constructors and stuff. In comes a dirname, a -D_GLIBCXX_USE_CXX11_ABI=0 and... Toto, I've a feeling we're not in Kansas anymore.
So what is happening? I copy a string expecting a deep copy, but then I do the dirname or manipulation on the copy and it messes up *both* strings. gcc/C++ I know you're a beast, but what's going on there? Thing is only possible if I cast away const from c_str - which of course is a doubtful operation - but there also seems to be some strange copy on write logic that the data pointers initially point to same memory location and only with first manipulation on the copy they start to point to different addresses.
I had no clue. And still don't have.4 -
if anyone is familiar with immer js or immutable js:
if the producer copies the base state to nextState, and nextState is a const, doesnt that defeat the purpose?
I mean you're going for immutability, which is great for say an undo function, or for finding bugs, but what are you doing with all these immutable values now hanging around in memory?
I assume each new state returned is being pushed onto an array? (because you cant stuff it into nextState because nextState is immutable).
Wont this lead to memory usage increasing over a user session, the longer the session lasts?
I feel like I'm misunderstanding some core concept here.
edit: also what the hell is structural sharing?18 -
I'm ok with almost every language.
But this "everything is a function" concept of JavaScript always give me that "kill me painless and quick" itch !!!#":":/#*%¢|°°

One of my least favourite parts of the world of programming is the "there's a usecase for everything" attitude. Like take this part of "You don't know Javascript" https://github.com/getify/...
> But var is still useful in that it communicates "this variable will be seen by a wider scope". Both declaration forms can be appropriate in any given part of a program, depending on the circumstances.
Now you would imagine that after this comment the author added a good example of this or at least had a reference to another part of the book where it showed this, but nope it goes on to include this note:
> It's very common to suggest that var should be avoided in favor of let (or const!), generally because of perceived confusion over how the scoping behavior of var has worked since the beginning of JS. I believe this to be overly restrictive advice and ultimately unhelpful. It's assuming you are unable to learn and use a feature properly in combination with other features. I believe you can and should learn any features available, and use them where appropriate!
Which again, "durr there's a usecase for this feature" or rather it's coming with basically an insult towards people who don't think you should use var without actually addressing anything. And what usually happens when someone tries to "there's a usecase for everything" is to either be really vague, or come up with some silly thing that you "might" do. -
I'm reading some react/typescript code and I haven't work much with any other language or paradigm where I might have a function return multiple objects that are different types
e.g.
const { sna, foo, bar } = useWhatever();
I mean I guess it's just unpacking properties from the actual return object but that isn't apparent to a newcomer at a glance (if I remember correctly)

Javascript really needs a way to define consts for a block 1 level up.
So instead of
const el = wide ? els.wide : els.tall
You can do
if (wide) const el = els.wide
if (!els) const el = els.tall
// etc..
Just makes chaining and backup values way easier than inline conditionals 🤔15 -
Couldn't find it on Google but does Node 6.9.1 support ES6 syntax and const, let, etc?

update on this
https://devrant.com/rants/1617751/...
My first interview was kinda okay, I think I'm not in the mood to join them as well. They have to create a web app and they are considering Angular and React but they're more favorable to Angular which I haven't used yet.
Second went pretty well as per my expectation, those guys using React, Vue in which I'm more interested and they seemed friendly to me. Instead of stupid questions (tell me about yourself bla bla bla), they asked the only logical question which was more related to work and my experience. In the end, they asked me about my salary expectations and joining period, and I'm feeling positive about it.
Now I've to wait for next week to get a response from both interviews.1 -
imagine building an app using javascript(react-native) that get list of skills which will be displayed to the user to select and the same list displayed as interest for the user to do the same if you try to treat them seperately but from the same source you get a shit result e.g
const list = responseFromApi;//array of object
let skills = list;;
let interest = list;
skills.checked = true;
interest is changed and the list constant variable is changed the values change were ever the list variable is assign to a variable and the variable is tempered.
the above code was the fustration i got with javascript when i didnt know of the mutation guy.
Mutation is a nightmare never knew javascript object are passed by reference which make them mutable this sucks....
another crazy behavior below though the same;
const person = {name:'Dan',age:43} //object
let person0 = person;
let person1 = person;
person1.name = 'David'
the value of both person0 and person get change.
this is madness .3 -

I have to say, I was excited about const and let, but seeing const written 10 times stacked on top of itself makes me wish it was just var. It's too long. If you are going to shorten a word - go all the way.1

rust can't even do rustfmt properly
it just does things unadvertised
like reorder_impl_lines which is described as putting type and const on top of files adds new lines between fn declarations and that's not disclosed anywhere. ffs took me a while to figure it out
and chain_width should be different for fn calls and match statements. because newlining multiple fn calls makes it readable, but newlining match statements and wrapping them in {} does not / makes it ugly. there is match_arm_blocks but it still newlines random stuff awkwardly, raaghh
I thought hey so cool I can write without caring about formatting and just press Ctrl + shift + i and all done but now I'm arguing with the formatter and the settings available suck and are poorly described. please don't write a formatting documentation with no examples, wtf? And disclose everything it does, preferably with consistent language so I can search the page (some of the descriptions say new line others call a new line a break. thanks)1 -

So here the function that does same thing as new operator in javascript:
// we define our function Person that assigns properties to THIS that points to some object
const Person = function(name, lastName) {
this.name = name;
this.lastName = lastName;
}
// in Person prototype property we define our functions
Person.prototype.getName = function() {
return this.name;
}
Person.prototype.getLastName = function() {
return this.lastName;
}
// function that simulates new operator
// first argument is a function that would act as constructor
// second argument is an arguments that would be passed to constructor
function New(func, ...args) {
// with Object.create() we create a new object and assign [[__proto__]] from "func" prototype property
let object = Object.create(func.prototype);
// here we're calling "func" with THIS pointing to object
func.apply(object, args);
// then we return it
return object;
}
let person = New(Person, "Name", "LastName");
console.dir(person);
// so this is how prototype OOP works in javascript6 -
Trying to figure out how the below code works. Everything is straight forward. The code works as I ran it in qbasic in dos emulator.
But for the life of me I cannot figure out wth cap1 and cap2 are. I debugged the code and saw values being set, but I cannot figure out where the data is coming from. I assume it is somehow related to the function declarations. Been 20 years since I did anything with qbasic. Maybe some other old fogie can tell me what is going on here:
DECLARE FUNCTION integrate (sample, cap, tc)
DECLARE FUNCTION differentiate (sample, cap, tc)
COMMON SHARED accumulator
CONST pi = 3.14159
SCREEN 9: CLS
FOR timeConstant = 10 TO 600 STEP 100
accumulator = 0
FOR a = 0 TO 22 STEP .01
wave = 0
FOR h = 1 TO 10
wave = wave + SIN(a * h) / h
NEXT h
lopass = integrate(wave, cap1, timeConstant)
IF wave > lopass THEN
trigger = 1
ELSE
trigger = 0
END IF
hipass = differentiate(trigger, cap2, 20)
PSET (a * 30, 50 - wave * 20), 15
PSET (a * 30, 50 - lopass * 20), 14
PSET (a * 30, 100 + timeConstant / 4 - trigger * 15), 2
PSET (a * 30, 270 - hipass * 20), 15
NEXT a
NEXT timeConstant
END
FUNCTION differentiate (sample, accumulator, tc) STATIC
fsample = tc
leakage = 1 - EXP(-2 * pi * 1 / fsample)
capAvg = leakage * accumulator
accumulator = accumulator - capAvg + sample
differentiate = sample - capAvg
END FUNCTION
FUNCTION integrate (sample, accumulator, tc) STATIC
fsample = tc
leakage = 1 - EXP(-2 * pi * 1 / fsample)
capAvg = leakage * accumulator
accumulator = accumulator - capAvg + sample
integrate = capAvg
END FUNCTION
The output looks like the image.

Here's a fun fact (which actually will be accompanied with a source) about node.js. When you import or require a module it will be imported as a singleton. Or put another way, ```export const Foo = { };``` is one of the simplest* and most readable singletons you can have in that runtime. And of course here's the thing you always should be asking for when people make a claim like this https://nodejs.org/api/...
So why write this? Well some of you might feel inclined to write a medium (or other) post about "design patterns in Javascript" where you basically just translate the GOF book from Java to Javascript and now you have something that isn't just awkwardly translated Java code! -

As hard as I fucking try, my stumbling block, every fucking time is exports/imports. I can't wrap my head around them, at all.
What do you use in browser vs in node?
Whats the *most commonly used standard*?
Whats the difference between "modules.export = Foo;"
vs "exports.Foo = Foo;"
what about
export class Foo? Is that the same as modules.export or export.Foo?
Look at this shit...
import FooComponent from "./Foo";
export default Foo
const Foo = require("./foo")
const Foo = require("./foo.js").Foo
import { Foo } from "./Foo.js";
And probably a dozen others I don't know about.
Why does there have to be so many fucking ways to do a fucking import/export?
What the fuck is going on here?8 -
JavaScript still doesn't have proper types, but eslint insists that I should use let and const instead of var. Thanks for the hint, but when I care to code properly, I will use TypeScript, otherwise I don't care.

tldr: Fuck webpack with a big rusty pipe.
I have a class and in the construct a method is called with an imported value as the argument. This imported value is declared like this:

Why on earth would you create an entire new HTMLImageElement in the javascript file just to get the width and height of an image and never render it to the DOM. FFS use MS Paint, 3D Paint or ANY OTHER IMAGE EDITING SOFTWARE to get the size.
Seriously you over engineered the shit out of the easiest const you'll ever write in JavaScript.
And for the record, the width and height of the image used are only used in formulas which produce the actual width and height of the mock buttons that get drawn onto the canvas element. And don't worry, the click event handler for these mock buttons is actually the click event handler for the canvas...which checks the coordinates of where the click was made on the canvas. And if the click is over where the button is drawn in, congrats you clicked the button. -
