“Any application that can be written in JavaScript, will eventually be written in JavaScript.” — Jeff Atwood
Fast-forward 20 years, a plane crashes, they find and open the black box and in the flight logs they can see the cause clearly: ”undefined is not a function”.14 -
LONG RANT AHEAD!
In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.
mvn clean && mvn install
same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.
mvn clean && mvn install
the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...
Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...
I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.11 -
Teacher: Homework for next time is to make 2 web pages with three javascript.

Me: What's "three JavaScript"
T: undefined
M: Do you mean three files?
T: No, I mean three JavaScript.
M: Okay, so let's go with five CSS and twelve HTML as well then...
Please, go somewhere else when you can't explain your OWN HOMEWORK ASSIGNMENT. Holy fuck.16 -
StackOverflow: let's marginalize your "problem" and focus on the real issue at hand, which is that line 4 doesn't conform to the language standards and thus will lead to undefined behavior on a single kind of 8-bit microcontroller made in 1984 that is no longer in use.5

TL;DR; If you do something very good you tend to compensate and give yourself a free pass to do not so good
It happens to me in software when I accomplish something really fast, like a bumpy process that is undefined and in most cases should take X amount of time, but due to luck + experience + right mindset I get it done like 5 times faster...

IF LIVES DEPEND ON A SYSTEM
1. Code review, collaboration, and knowledge sharing (each hour of code review saves 33 hours of maintenance)
2. TDD (40% — 80% reduction in production bug density)
3. Daily continuous integration (large code merges are a major source of bugs)
4. Minimize developer interruptions (an interrupted task takes twice as long and contains twice as many defects)
5. Linting (catches many typo and undefined variable bugs that static types could catch, as well as a host of stylistic issues that correlate with bug creation, such as accidentally assigning when you meant to compare)
6. Reduce complexity & improve modularity -- complex code is harder to understand, test, and maintain

I hate all of these rants about JavaScript being a terrible language.
In reality, it's one of the easiest languages to work with. This makes it easier for new programmers to write messy code, but is it the language's fault?
People get mad about the things that happen when you multiply "undefined" and a string...what do you expect?
You also have the freedom to choose from a variety of tools the community has created to solve existing problems. People just don't realize that they don't *have* to learn everything, you just learn as you need them.
Don't blame JavaScript for you bad programming, terrible type conversion needs, and great tooling.23 -
"Errors? Won't happen to me!"
One of my first jobs was to finish and maintain a program, that was made by a guy who had a real genius image among others. Years later, people said "oh him, that smart guy."
I never met him, but that's what i heard.
However, he was not only smart, but it seems he was also very confident. That's what i deduct from his code.
He didn't use catch-blocks. They were all empty. Not even logged.
If errors appeared , it was not possible to see what happened and where and why. The program would continue it's execution and if following steps could not work, because there had been an unnoticed exception, it would just throw another unnoticed exception and at some point, end in an undefined state.5 -

I love Linux, but its community can be so full of incompetent assholes..
Just now I asked in Freenode ##linux how to get the process ID of my current running process in bash. I got my answer - it's a shell built-in called "$$".
Then people start to nitpick some more - why do you need it? How is that different from an exit? - to which my response was.. well I know the whole idea behind exit codes, and I'd use it whenever possible, in all defined behavior that allows my program to terminate itself whenever it can. This pidfile however would be used to exit itself and provide diagnostic information whenever the program enters undefined behavior - a segfault in C language. Scenarios in which I don't have full control over the script's behavior anymore, such as the system entering an unworkable state where the system stalled, still got some binaries in RAM but the rootfs got unwritable, such as now - very helpfully, thanks HP! - when my laptop likely overheated and shat itself. I issued sudo reboot into it, but even that wouldn't issue properly anymore due to the /sbin/poweroff binary becoming inaccessible too. I had to issue a hard power cycle.. one of the few times in which I'm thankful to HP for actually causing shit like this, lol.
Point is, that undefined behavior is what I'm trying to mitigate against. I certainly can't let any files other than diagnostics remain in nonvolatile storage like that, especially when their state should be predictable in order to ensure good operation (like files expressing whether the script is already running or not, i.e. lock files).
Back to that IRC chat. Aside from the answer, I got ridicule from people who probably don't even know how to properly compile a kernel. Ubuntu users, overconfident scum. Sometimes I feel like I should ask questions in channels like #archlinux only, where such incompetency is ridiculed on its own.13 -

Today I was wandering through the code of the project I work on. The project is on JS, turns out someone named an object key `undefined`. They had the wonderful idea since they didn't want to pass a key through on the side where the info stored in the object is used(or at least that's what I assume).
Look at the image. (not the actual implementation but you get it and it actually works if you want to try it)
👏🏼 I don't know who did it and I rather not git blame it, but pray to the 7 gods you never do something like that again while I'm around or you are going to be in need of prosthetic fingers to code again motherfucker.

I started two months ago a new role in a new company.
Together with 3 colleagues I manage a HUGE OpenStack platform (I’m talking about more than 300 customers, many petabytes of data, dozens of compute nodes 😍).
On Friday night a well-known multinational had the GREAT idea to update the software of one of the core components of the platform (Neutron).
Obviously it all went wrong and customers started to call and open tickets, so even if it was already past midnight we’ve been all called to arms.
As a workaround we had to rebuild ALL the networks, detach all the ports and reattach them to the VMs, with all the errors that came with this kind of operations, such as failing to get an internal/external IP, fail to boot etcetera.
What amuses me is the fact that the above-mentioned multinational just asked for logs with no solution (except for the above workaround) until Monday morning.
It has been a good weekend, i talked with professionals from all over the world, in various languages, and worked multi-tasking with two different computers, with a third that was used just to share my screen and VPN for the management network.
During this weekend I virtually met all the possible colleagues that I will meet in this new role, and it was pretty funny to see how they handle stress. (Badly if you ask)
I’ve been woken up at 7:30 after falling asleep at 6:45, I’ve slept 17 hours in 5 days, haven’t taken a shower in 5 days (I know, it happens, I worked from home) but it was worth it.
Not only and merely for the money (overtime work), but mainly for the job itself.
I love to handle this HUGE infrastructures for now, even if I think they have many limitations and many components could have been written better.
The best thing about this weekend was to meet a group of people from all over the country and the world that worked non-stop from Friday night until Wednesday night to solve the situation.
All of them understood me when I asked them questions, and didn’t treat me like the [insert random]science nerd that I am.
I felt like in the movies, in front of three monitors, working from the comfort of my chair, in my underwear, eating as fast as I could because I was constantly in call with someone.
Apart from that, WHAT THE FUCK WENT THROUGH YOUR HEAD TO DEPLOY AN UPDATE ON FRIDAY NIGHT, YOU FUCKING PIECE OF adorable man???
WHY COULDN’T YOU WAIT UNTIL MONDAY??? NOBODY USES THOSE SERVICES AT NIGHT APART FROM THE SCHEDULED JOBS!!!!!
I HOPE YOU’LL HAVE A LONG AND PROSPER LIFE, FULL OF JOY AND HAPPINESS5 -

In my first summer at my internship I was fixing up a PHP script that a previous developer wrote... It collected our customer's emails and sent them to MailChimp for marketing.
The SQL query to get the emails was pretty standard, but what he did next was not.
There were for loops nested 3 deep. The outer loop's counter was i. The inner was ii. And the deepest was iii. That alone made it hard to read, but for a couple years some iii's and ii's were mixed up when getting values for arrays. So it was even harder to tell what it was supposed to do.
The inner loop also started at i-20. This was so he could look through and see if an email was already included from that query and skip it. But he didn't check the bounds, so the first 20 times through the outer loop, the inner loop would throw `undefined index -20` errors.
In order to fix all this I did an order by on the query, and kept a last email variable that I used for comparison. Pretty basic. This also lowered it to just one loop.
I talk about it on a regular basis with my coworkers and we all laugh about it. I also bring it up when upper management thinks they can code, because that ex developer is now an executive. -
I spent more than an hour trying trying to debug why two functions were always returning undefined. I even put in conditional breakpoints and executed the statements to confirm the logic was correct.

So our university website was recently refurbished with new design. But fucking hell it's bad. Not only the whole website is full of bugs, the design choices are extremely poor.
Sometimes, when I open a course page, it opens a modal with undefined as it's title. And I have to click close button ten times to close the modal.
I can't even blame university. The guy was a former student and Uni probably trusted him. What a retard!5 -

I read this in stackoverflow today:
Welcome to every C/C++ programmers bestest friend: Undefined Behavior.
There is a lot that is not specified by the language standard, for a variety of reasons. This is one of them.
In general, whenever you encounter undefined behavior, anything might happen. The application may crash, it may freeze, it may eject your CD-ROM drive or make demons come out of your nose. It may format your harddrive or email all your porn to your grandmother.

Was forced to do some work on Windows this week (CAD tools that runs only on Windows). I spent a few days just setting up the tools. There were quite a few things I realized I forgot about Windows (as compared to Linux).
1) Installation times are down right horrific. What exactly are the installer doing for 10 minutes?
2) .NET is a cluster fuck. Not even Microsofts repair tool can fix it, but rather just hangs. I ended up using another tool to nuke it and reinstall.
3) Windows binary installs are insanely huge, thus, takes forever to download.
4) The registry is a pointless database that must have been written in hell with the single intent of destroying users will to live. The sole existence of the registry is another proof that completely incompetent engineers designed Windows.
5) Rebooting is the only way to solve many problems. This is another sure sign of a fundamentally fucked up OS design.
6) What the heck is wrong with the GUIs designers? The control panel must be the worst design ever. There are so many levels to get to a particular setting I'm getting dizzy. Nothing gets better by the illogical organisation.
7) Windows networking. A perversion of the tcp/ip stack that makes it virtually impossible to understand a damn thing about the current network configuration. There are at least 3 different places that effects the settings.
8) Windows command prompt. Why did they even bother to leave it in? The interpreter is as intelligent as retarded donut. You can't do anything with it, except typing "exit" and Google for another solution.
8) Updates. Why does it takes hundreds of updates per month to keep that thing safe?
9) Despite all updates that is flying out of Redmond like confetti, it is still necessary to install antivirus to keep the damn thing safe. That cost extra money, and further cost you by degrading performance of your hardware.
10) Window performance. Software runs like it was swimming in molasses. The final stab in the back on your hardware investment, and pretty much sends performance on your hardware back a few hundred bucks more.
11) Closed source is evil. If something crash consistently, you might find a forum that address the issues you have. Otherwise you're out of luck. On the other hand, it might be for the better. I imagine reading the code for Windows can lead to severe depression.
I'm lucky to be a Linux dev, and should probably not complain too much... But really, Windows, go get yourself hit by a truck and die. I won't miss you.14 -

Code comments #1: A way to document bad code that wasn't reduced to it's essentials and thus unreadable. Bad.
Code comments #2: A way to explain for non-programmers how the code works. Wrong place.
Code comments #3: Company policy. No one really knows why, but others do that, so we better do it to. The management sucks.
Code comments #4: Because some hip methodology/guru describes how to document code. After a few years, when the methodology has been (unofficially) forgotten, everyone still comments the code the same way. The old management sucked.
Code comments 5#: For insecure programmers who want to convince them self they understand the code they've written. Maybe apply at McDo?

The tons of undefined behaviour in C that ought to have been implementation defined instead, and increasingly sadistic compiler writers on the other side.
Like signed integer overflow that should just do what the underlying machine does, i.e. in practice, wrap around two's complement.
But the wierdest UB is when a C source code line has a non-matching ' or ". WTF, this should have been a compile time error!4 -
I love javascript, but sometimes it's just an incredibly stupid language, such as when undefined variables get interpreted as string literal "undefined" when concatenating strings. I like it better how, for example, PHP handles undefined values, that nulls just turn into "". Better still: typed languages, where most stupid mistakes are caught already at compilation, instead of having to spend hours to track down where that mysterious "undefined" comes from. As I said, I love javascript - because it is easy to code, flexible and forgiving in many ways. But I hate it for the exact same reason, for being such a sloppy fluffy...thing, and a bugger to debug. If javascript would be an animal, it would be a cute and cuddly cat that you instantly find adorable, but it's actually quite fat and lazy, plus its fur is littered with ticks and other bugs.12

Init Mud. (A poem)
A Giant Ball of Mud.
Haphazard in structure.
A sprawling, enthralling, duct-taped warning,
Of things to come.
Tumbling down a well-worn path
Of untamed growth and aftermath.
Into Spaghetti-code Jungle.
Where quick and dirty wins the day
And warnings spoken hold no sway
Or fall on deaf ears in the undergrowth.
Tumbling.
Gaining weight.
Bits stuck on.
Bytes taken out.
Patches,
On top of patches,
On top of obsolescence.
Hacked at, uploaded
All elegance eroded.
Made and remade
Then duplicated
Relocated
Refined and redesigned
Suffocated by expedient repair after expedient repair
The original self no longer there
Replaced by something
Unwieldy.
Design resigned to undefined
An architectural mystery
Whose function can no longer be
Seen or gleaned
From obfuscated in-betweens
Of classes
Made and remade
Duplicated.
Abused.
A squirming library of disused.
Pulled at, prodded, committed
Corners cut and parts omitted.
Bug ridden branches fused to a rotting core.
The structure...
The system...
The content...
Mud.1 -

So in the end I did 17 or 19 back-retry attempts in a row and the last one DID log me in.
Peachy.

VirusTotal's API could do with a make over.
Though it is quite nice actually, you're able to provide them with a hash of a file and (provided they've scanned it) VT is able to tell you what up to 60 different virus scanners thinks about the file (and how many scanners that has an opinion about it). Now if there's an error, like the file not having been scanned or the hash being incomplete, it give you some JSON back where there will be an error message that tells you the error and an error code of 0.. wait wh
Although since it's an API they also need give us plebs whose only got access to an API key that limits us to 4 requests pr minutes. Naturally when you try to do another request within a minute of your limit the response you get is absolutely nothing what so ever. "" Naturally.
And of course the same response should be given when the API key you provide isn't valid. Who needs errors amiright?
No wonder JSON.parse kept throwing exceptions

Why are some of my previous rants tagged with "undefined"? I definitely don't remember doing that 🤔2

I don't know how to tell but my love to JavaScript is undefined. I can't stop const sharing this information wherever i am.5

During my first semester of CS we were mostly using MatLab for basal scripting - assigning variables, learning about scope, that type of thing. I was excited to start learning programming but wanted to actually make something rather than reversing arrays and incrementing counters for weeks.
I discovered the image() function which takes a float[][] matrix and displays it as an image. I generated my arrays of random numbers and made a simple nested loop where I iterated over each element, averaging it with its neighbours, and - it worked on the first run! I made a freaking noise and blur filter!
That rush of planning it out, making it, and seeing it work I think is my main drive in coding. All the hours of undefined-but-they-are-tho import paths and mystery segfaults are worth it once there is that moment of "it lives!". -

Most of my time coding in Javascript goes to handling null checks and fixing crashes caused due to missed null checks.
`"abc" is undefined` is an error which I must have seen more number of times than any other bug in console and even in real life.2 -
Here’s a snippet of code that I found in our production codebase. I found this while fixing a bug. This is not part of the bug though but I see this a problem. Should I say this to my senior that his logic is off here?
First he doesnt have to do explicitly strict comparison since the return type is boolean and it could be true or false. Also the returnUrl will alway be undefined because redirectIfUserLoggedIn is called first before it was set.
He dosent like me. Hell get mad for sure. I think ill let this go.

How to get your website reach out people with no advertisements!?
1. Once it's built, make another mock up by changing a few main highlighted words to "(null)" or undefined!
2. Then send the link to any person in the software development field, anonymously!
That person will take care of the rest!
Note: don't forget to change the mock up with the original after u have sent the link!4 -

What paradoxes taught me.
Perhaps each time a paradox is encountered in mathematics, there is a useful distinction or mathematical tool hiding in plain sight, one that hasn't be discovered or utilized. For cursory evidence I give you: division by zero, the speed of an arrow at any point in flight, and calculus.
Maybe this isn't true for some paradoxes, or even most, but as time goes on I suspect people will discover it is more true than they might have thought.
Undefined behavior and results aren't nonsense: They look to me like golden seams to be explored for possible utility when approached from uncommon angles with uncommon problems.6 -
Real story:
Started fixing one file in one repo, build, doesn't build, go into other repo fix just one file there, but first I need to make myself a toolchain, making of toolchain fails because it depends on some dirty fix in the file I was fixing, refactor and clean that to a proper state, fuck yeah toolchain builds, source toolchain run make now, breaks with undefined reference, no time to debug plus fuck this automake, remove it, make a makefile, builds fuck yeah, shit now unittest are failing because why not, refactored that makefile as well, everything compiles, automate the test fully so that they are ran on the target out of make just because I'm a nice guy, fuck yeah everything works, commit this repo, commit other repo, review time, one of the guys gave up, the other one did it properly, found some shit there, fix that, done, merge, triggers CI fucking pass
All of this was done in 3h, Talk about efficiency -

Hi everyone... Great to be back but not feeling so great. I keep feeling... "tired", "bored", like everything I do has no fucking meaning. Like I lost all of that fun I had when I was making my own projects. I get home at 6PM from work and it feels like time passes by so fast. I can't even muster up the enthusiasm to start my own personal projects.
What do you do when you feel like this? How can I get back my enthusiasm?13 -
I feel retarded. Just spent a good solid 15 minutes trying to figure out what was wrong:

You can say you know a computer language to a decent level when you can in fact make useful programs with it.
For example, I can say I know JavaScript to a basic level. I know its basic core functionality by heart (which can't be said for some people I know), such as:
- it manipulates the DOM, the DOM has Element, Nodes, TextNodes (all to be found on W3C documents with its own specs)
- useful functions are:
getElementById()
getElementsByClassName()
Also knowing that these return either HTMLElementCollection or NodeCollection because you have to iterate over it differently then
- element.textContent
- == and ===
- dynamic typing
- closures
- avoid global variables
- nodes have parentNodes
- isNaN, undefined
- arr.push()
- arguments don't have explicit types defined
- etc.
Using this knowledge I built an antispam script for a particular server. It's good to know the model of a language, that it sits in your head and that you can use and understand the constructs when you want and how you want.1 -

Hey, I have a cool idea about a new way to solve a problem our users are having!
Type type type, now I have a working prototype! Show it to the team, everyone loves it. Polish it a little, it works really great!
Now let's test it on an iPad like the ones our users have... Nope, nothing works, undefined is not a function.
F*CK YOU SAFARI, you're why we can't have nice things. 😤 -
I was in dependency hell for two days.
Im a junior working in a team creating an ember app. Suddenly a main component refuses to work since an addon threw "EmberObject undefined"... Nobody could reproduce it and we where out of ideas, so I tried fixing it for 2days (7h total). I finally got it working after updating yarn :D
It never felt so good working again :) -

I am going to set up my own mini company and I am wondering about the name I will choose. Definitely want something strange and sarcastic like "undefined" or "null"...but these two are already taken? I was thinking about "1;DROP TABLE users" but it is too long. Any ideas out there? xD2

Focused on debugging Javascript after being asked for help. Original developer narrowed it down to an if statement. It was acting like the if statement was assigning the variable and causing undefined. Tested console.log before evaluation. Tried !== instead of != and same thing. Even swapped undefined and variable so it would try to assign a variable named undefined instead... It took way too long for the both of us to realize the word "let" in front of the variable on the line withing the if statement block... It overwrite the variable the moment it entered the block.... FML.1

In the darkest dankest parts of the code, I have discovered a way to get the tag UNDEFINED to show up in this rant. They call things that are unknown a black box. But you see, if you have a good enough shot gun, you can begin to blow enough holes through the box to figure out what's inside. I never said that whatever was inside the box was going to make it out... I just wanna get a good idea of what was inside.4

jesus christ.
we just removed a parameter check in function bool f(). because its actually raised exceptions. that in the case when data is inconsistent.
sooo. in a function that returns a bool, we now return false when data we need to determine the result is missing.
i wonder when the first guy will find out what that means for calling the function with NOT f() and undefined data, its always gonna be true.. *facepalm*. -
"Just start ahead"
I am supposed to transform calls from one api to another one. Yet there's no documentation, ambiguous code statements, no examples of what values are contained -- but sure, let me just start assuming how the whole thing is supposed to work. That won't lead us more into a murky waters at all.
Even more frustrating: We own the api. We should be able to tell by the access logs how we are queried. Yet for some reason, access logs cannot be accessed and I shall "just work from the swagger defintion".
Well, that swagger definition is broken, its example are shit (somebody liked to use undefined in optional fields, making me wonder even more what the heck is going on here), and I have no idea of what I am doing. Fun times.3 -
What the f*...
SomeType {
var something = {
somethingElse: "blah",
whatever: "halb"
}
var doStuff = function() {
this.something.whatever = "foo";
}
}
Based on what fucking logic are you claiming "something" is _undefined_ while running doStuff()??? What the fuck is wrong with you??? It's a freakin' static context!!!! "SOMETHING" IS DESIGNED TO BE DEFINED ! ! ! ! !8 -
Maybe not the worst but the worst one I can remember for sure and it happened recently. I may or may not have spent 4 hours with another developer working out why my script didn't work.. to realise that I had swapped the underscore in a method name for a period. No wonder everything came back undefined when I was dotting into a method that didn't exist 🤦🏻♀️ my only highlight was that the more experienced dev was there with me and he also couldn't find it for all that time lmao. I did briefly contemplate calling my University and asking them to just take my diploma back, I don't deserve it lmfao2

So at the HS I go to, there are 4~5 programmers (only 3 real "experienced" ones though including me).
So coming from JS & Python, I hate Java (especially for robotics) and prefer C++ (through some basic tutorials).
Programmer Nº2 is great at everything, loves Objective-C, Swift, Python, and to a certain extent Java.
Programmer Nº3 loves Python and used to do lots of C#, dislikes Java and appreciates Go (not much experience).
So naturally I get shit on (playfully) because of my JS background, because they don't understand many aspects of it. They hate the DOM manipulation (which is dislike too tbh), but especially OOP in JS, string/int manipulation, certain methods and HOISTING.
So, IDK if Java or C++ (super limited in them) have hoisting, but if you don't know what hoisting is, it means that you can define a variable, use it before assigning a value, and the code will still run. It also means that you can use a variable before defining it and assigning a value to it.
So in JS you can define a variable, assign no value to it, use it in a function for instance, and then assign a value after calling the function, like so:
var y;
function hi(x) {
console.log(y + " " + x);
y = "hi";
}
hi("bob");
output: undefined bob
And, as said before, you can use a variable before defining it - without causing any errors.
Since I can barely express myself, here is an example:
JS code:
function hi(x) {
console.log(y + " " + x);
var y = "hi";
}
hi("bob");
output: undefined bob
So my friends are like: WTF?? Doesn't that produce an Error of some sort?
- Well no kiddo, it might not make sense to you, and you can trash talk JS and its architecture all you want, but this somehow, sometimes IS useful.
No real point/punchline to this story, but it makes me laugh (internally), and since I really want to say it and my family is shit with computers, I posted it here.
I know many of you hate JS BTW, so I'm prepared to get trashed/downvoted back to the Earth's crust like a StackOverflow question.6 -
I expect somebody else has chosen this as well, but anyway:
Async.<any-function>, cause they brought me out of callback hell and taught me the undefined ways async...arghhhh fuck -
So I'm supposed to implement a date range. Easy right?
Wrong. It's not implemented into Angular-material (even though it's quite a standard thing to do). There is a third party solution - that works with Angular 8. We're still on Angular 7.
So either we do the update, or we just put two date-picker side by side. I propose the two solutions. Head of UX come to me to say "every change have to go through UX".
Then, she's unpleasantly complaining that "that's why we do grooming" and "why haven't been detected before"... Ugh, those people job is to tell me where to put my button and they think they're important. I don't know, we work in an unprevisible world?
I tried the update. I get stupid, angular-style error like "'green is undefined'", and countless stupid dependancies incompatibilities.
I have a degree in usability. I didn't do UX because it's... not interesting. I love programming. I hate Angular.5 -
How do you know that you are stuck in a job without longterm perspective (besides some undefined gut feeling)?
And what to do then? It seems to me, only possible action is to change job. Is there any, less extreme, alternative? -
An undefined ArrayList coupled with NullPointerExceptions because of it really know how to raise your blood pressure up.
Spent almost 1 hour trying to figure out why and all I needed to do was look a couple lines above.
But I guess that's what 4am development is all about -
try{
If(!res || typeof res == undefined || res == undefined){}
}catch(err){
// you just had to throw an error
} -
Working with Angular is like walking in a minefield.
Here, I get this ERROR in Cannot read property 'members' of undefined.
Of course, apparently stacktraces or clear error messages are optional for the Angular team.
Also, I looked for 'members' in my project. Hint, it's nowhere to be find.

Why the pointer of member function so special.
trying make a non-template class that like std::function but simpler:
1. wrap static function pointer.
2. wrap class member function pointer and the class object pointer.
3. WITHOUT ALLOCATE MEMORY.
I can't store member function pointer because the size is undefined?! -
Okay I always found these js weirdnesses that you see in memes more or less logical if you think about it, but so far I could not find any logic behind this:
true&&undefined
>undefined
false&&undefined
>false
can anyone explain wtf they thought about there? undefined is falsy so why not just convert it to boolean implicitly!5 -

Me: I found the problem. The function call is being given a reference to an undefined variable as an argument. The quotes around that argument were accidentally omitted; it's supposed to be a string.

Decided to try the beta build of WP 5.0 today to get a feel for Gutenberg block development, but it's not building confidence. Following the examples in the Handbook (Link: https://wordpress.org/gutenberg/...) and it's failing when trying to set up the rich text editor because apparently the object it relies upon is undefined. Been trying to track down the code for the basic paragraph box for an hour or so now so I can see how it's doing things, and haven't turned up anything useful.

While building this site I decide to check if it works in internet explorer (you know, would be kinda nice) only to find out that apparently even edge does not support the js notation:

Javascript is my main tool at work right now, Typescript to be precise. It never ceases to amaze me, I guess as most of you.
What I've encountered recently still doesn't make sense to me but it seemingly works:
function a(){
someString && someFunction()
// other stuff ...
}
someString can be a string or undefined, someFunction can be a function or undefined.
How is that valid Javascript, without an assignment? Haven't found any explanation yet.23 -

Dear frontend dev,
if you can't check whether a variable is defined or not, why do i have to change the back end to accept urlparam='undefined' as valid and replace it with your default value in my backend? Why are you afraid of 40X's? You should be interested in the bugs of your code.
It feels awful to have a middleware in place catching all errors and replacing them with empty 200 responses 😭. All of this because you don't fucking ensure your variables exist before use.3 -

pkg/proto/notify/notify_grpc.pb.go:71:30: undefined: grpc.ServiceRegistrar

Axios docs recommend me to use catch() callback for server error
- Not working
Then in git issue someone told to provide error callback as second parameter in then()
- Not working
And I just sit here wondering why it return undefined result when the server return 400 :s6 -
You should leave undefined to the browser and keep null for yourself.
Don't '' var keep = undefined; ",
Do " var keep = null; "1 -
{
regular: function () { return this }, // ok
arrow: () => { return this } // you mean undefined?

NPM version : 10
React-Native Library : react-native-get-music-files
Installation :
npm i --save react-native-get-music-files
rnpm link
Things I Have Already Tried :
rnpm link react-native-get-music-files
react-native link
npm install
react-native run-android
REINSTALLING
MAKING A NEW PROJECT
Details :
Its documentation says add import com.reactlibrary.RNReatNativeGetMusicFilesPackage; but when automatically linking , it adds com.cinder72.musicfiles.RNReactNativeGetMusicFilesPackage;
Manually it is showing com.reactlibrary.RNReatN... is not found.
Automatically everything is working fine.
Error :
In the react-native-get-music-files/index.js
import { NativeModules, Platform } from 'react-native';
const { RNReactNativeGetMusicFiles } = NativeModules;
const MusicFiles = {
getAll(options){
return new Promise((resolve, reject) => {
if(Platform.OS === "android"){
RNReactNativeGetMusicFiles.getAll(options,(tracks) => {
resolve(tracks);
},(error) => {
resolve(error);
});
}else{
RNReactNativeGetMusicFiles.getAll(options, (tracks) => {
if(tracks.length > 0){
resolve(tracks);
}else{
resolve("Error, you don't have any tracks");
}
});
}
});
}
}
export default MusicFiles;
It says RNReactNativeGetMusic files is undefined.
I tried console log NATIVEMODULES and it shows nothing as RNReactNativeGetMusic or anything similar.2 -
I am using MERN to develop a poll app. I have 6 collections in my database. I have an API for each collection, 4 of those API returns the data whereas the other 2 return 'undefined'. What is the issue I am facing? Is MongoDB not allowing me to use more than 4 collections?6

So I have a MEAN app that is super simple just basic CRUD operations.
Everything works fine. Decide to extend it by bringing values over into fields on an Edit page. More work than I thought it would be but got it working, just passed values through an array in the URL. Pretty simple. So then I click save and it's broken. _id is apparently now undefined. Oh I posted it on the Javascript chat on SO and got nothing, instead everyone is talking about porn folders, a tweet, a random picture that looks like either a woman doing oral to a guy or a guy reading a book, and now Obamacare. FFS just answer my damn question >.< So I post it on SO itself and still crickets there. Worst part is I know its something simple I just don't know what it is because I'm still new to programming in general only been a few months in a bootcamp just learning the basics of MEAN stack (which I do like a lot tbh)
Man SO is so frustrating.
