Hello, I just want to let you know I'm working on a 15 year old product and it is currently in production.
It uses Angular.js and one of the earliest versions of React.js. I cannot use ES6, we don't have Babel, no JSX syntax, no CSS preprocessor. No webpack.
I must support browser since IE6 with an ES3 syntax. (luckily I got some some polyfills for an ES5 syntax)
When I build a component I have to call React.createClass and React.createElement.
The render() function is basically a nested pile of React.createElement.
There is no documentation for this product, no tests, no anything.
I had to reverse engineer it in order to understand how it works.
The code base uses mixed programming styles and naming conventions, plus thousands of little js files.
Oh and obviously no hot reload, every time I make a change I have to restart everything.
Please, send help.
I'm in danger.
Sincerely,
An underpaid developer

I'm not crying, you are crying...19 -
I really feel sad for the person that is going to manage my code in future :(

LONELINESS IS REAL
I am a freshman in a university ( about to complete my first year ) with a girl to boy ratio of around 1:10. During my first semester I was spending a lot of time with friends, chatting up with people and making connections. Due to this my productivity as a dev, if I am even capable of being called that decreased ( I was not a developer before joining , but I had an aim of being one , esp at least the best in my batch ) after 1st year. In retrospect I did nothing productive till 3 months out of 4 in my first sem and the guilt hit me hard . During the last month I had to catch up with my much neglected studies and all I had done was a little bit of html and css, and barely scratched the surface of js( please don't judge me for this :) , I had to start somewhere < although I learned a little bit of C++ > ). BUT I WAS A HAPPY CUNT, and had no sign of lonelines. Now during this sem , I had made progress ( learn js with es6 syntax and still learning, did c++ and extended my knowledge ) . Currently I am working on my Vue full stack app ( along with express and some websocket library , TBD ) < yeh I learnt some backend too > , and increasing my knowledge of dsa using clrs. Although my productivity has increased manifolds but I know feel the need of closure. I am kinda happy with the fact that I know a lot of people around here ( thanks to my extroverted 1st semester ) but sometimes it hits me hard at night when I don't have a monitor to drown my eyes and thoughts in. I have increased my academic performance too but I need someone to share and express my feelings with. I could have made a girlfriend earlier but now most of them are taken and I have lost touch. But believe me, all I want is a companion to spend these lonely days and night ( not talking about as a friend ). Staying away from home isnt easy you know...m :(
KUDOS TO DEVRANT FOR DEVELOPING A COMMUNITY WHERE PEOPLE LIKE ME CAN FEEL SAFE IN OUR NATURAL HABITAT. I COULDN'T HAVE EXPRESSED MY FEELINGS ANYWHERE ELSE EXCEPT IN A PERSONAL BLOG ( where no one would have read it )
PS1: I apologise if I sounded arrogant about any of my skill, I didn't mean that way. I ain't even that good, just kinda proud of myself a little for achieving something I couldn't have thought.
PS2: Any type of suggestions and help is much appreciated ( considering I am a college student who went into some serious development 4 months ago , I am pretty impressionable ;) )
PS3: Please don't confuse this with depression. I am HAPPY BUT LONELY
PS4: Is there a way so that I can change my username?16 -
I come from PHP and have been using jQuery as a crutch for years. I've dabbled in Node and obviously writing some vanilla JS is unavoidable, but now I'm starting to use ES6 with Babel and VueJS and the more I dig in, the more I hate javascript. Everything is an object (null, array), there seems to be a few gotchas with math (including the one pictured), nothing is strongly typed but types are very important (for instance, you can't loop an object and an array using the same code), and there are a lot of inconsistencies/functions missing. ucwords for instance. Why doesn't that exist? typeof only returns object, but Array.isArray and Object.isObject work fine. I'm going to give typescript a go soon and cross my fingers.

Frustrated, tired and a bit lost.
I'm a "Senior PHP Backend Dev", which includes not the greatest tech stack nor the best job title, but it pays fine, and the company is awesome to work for.
I suck at writing features, but I'm great at bitching, and I easily put complex abstract concepts into usable models. So I'm also QA, tester, tech lead, database architect, whatever.
That makes writing PHP less annoying, because I create the rules, and whip devs around when they forget a return type definition or forget to handle an edge case. But I don't write a lot of code anymore, I mostly read (bad) code.
Lately I REALLY feel like doing something else... problem is that I know JS/ES6, but really dislike React/Vue and the whole crappy modern frontend toolchainchootrain of babelifyingwebpackingyarnballs. I know Python/Tensorflow/etc, but don't feel like I want to go into data science or AI. And then I'm awesome at the shit no one uses, like Haskell, Go and Rust (and worse).
I got a job offer which combines a very interesting PHP codebase with a Java infrastructure, where I could learn a lot... and I'm kind of tempted.
Problem is, everyone always shits on Java. I always made a bit of fun of Java myself. Don't even know exactly why, probably some really cruel instinct which causes kids to bully the least popular kid.
I know the basics, I've written the hello world, and a small backend app for a personal project. I know how strict and verbose it can be. I love the strictness in Haskell and Rust.... but those are both also quite terse.
Should I become a Java dev? I'm not talking about Android SDK, but an insane enterprise codebase at a life sciences corporation.
To the pro Java devs: What are the best and worst things about your job, about the weekly processes, about the toolchains? Have you ever considered other languages? Do you unconditionally love and believe in Java, or do you believe Swift, Kotlin, Scala or whatever will eventually make it completely obsolete?
Will Java hasten my decline into the cynical neckbeard I was always destined to be?
There are a lot more fun langauges, but looking at realistic demand and career value...20 -

Does anyone feel overwhelmed by all the new technologies? It's like every developer nowadays code in JS, and knows ES6, React, webpack, babel by heart. I have been working in Java for less than a decade and sometimes feel like I can't catch up. Even in Java ecosystem there is now Scala, Groovy, Gradle, Kotlin... Not to mention other languages like Python, Swift... How do you guys have time to pick up everything?? 😖7
-
The JavaScript everywhere trend.
Sure it's possible and the language develops at a fast pace since ES6 but JS like any other language just is not suited for everything. I think JS will stay in server side automation and as scripting language for customisation but not how it is abused now in electron or even node.js.
There will be better solutions if they are not already there.10 -
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}`;
};

I've kinda ghosted DevRant so here's an update:
VueJS is pretty good and I'm happy using it, but it seems I need to start with React soon to gain more business partnerships :( I'm down to learn React, but I'd rather jump into Typescript or stick with Vue.
Webpack is cool and I like it more than my previous Gulp implementation.
Docker has become much more usable in the last 2 years, but it's still garbage on Windows/Mac when running an application that runs on Symfony...without docker-sync. File interactions are just too slow for some of my enterprise apps. docker-sync was a life-saver.
I wish I had swapped ALL links to XHR requests long ago. This pseudo-SPA architecture that I've got now (still server-side rendered) is pretty good. It allows my server to do what servers do best, while eliminating the overhead of reloading CSS/JS on every request. I wrote an ES6 component for this: https://github.com/HTMLGuyLLC/... - Frankly, I could give a shit if you think it's dumb or hate it or think I'm dumb, but I'd love to hear any ideas for improving it (it's open source for a reason). I've been told my script is super helpful for people who have Shopify sites and can't change the backend. I use it to modernize older apps.
ContentBuilder.js has improved a ton in the last year and they're having a sale that ends today if you have a need for something like that, take a look: https://innovastudio.com/content-bu...
I bought and returned a 2019 Macbook pro with i9. I'll stick with my 2015 until we see what's in store for 2020. Apple has really stopped making great products ever since Jobs died, and I can't imagine that he was THAT important to the company. Any idiot on the street can you tell you several ways they could improve the latest models...for instance, how about feedback when you click buttons in the touchbar? How about a skinnier trackpad so your wrists aren't constantly on it? How about always-available audio and brightness buttons? How about better ports...How about a bezel-less screen? How about better arrow keys so you can easily click the up arrow without hitting shift all the time? How about a keyboard that doesn't suck? I did love touch ID though, and the laptop was much lighter.
The Logitech MX Master 3 mouse was just released. I love my 2s, so I just ordered it. We'll see how it is!
PHPStorm still hasn't fixed a couple things that are bothering me with the terminal: can't reorder tabs with drag and drop, tabs are saved but don't reconnect to the server so the title is wrong if you reopen a project and forget that the terminal tabs are from your last session and no longer connected. I've accidentally tried to run scripts locally that were meant for the server more than once...
I just found out this exists: https://caniuse.email/
I'm going to be looking into Kubernetes soon. I keep seeing the name (docker for mac, digitalocean) so I'm curious.
AWS S3 Glacier is still a bitch to work with in 2019...wtf? Having to setup a Python script with a bunch of dependencies in order to remove all items in a vault before you can delete it is dumb. It's like they said "how can we make it difficult for people to remove shit so we can keep charging them forever?". I finally removed almost 2TB of data, but my computer had to run that script for a day....so dumb...6 -

hey guys,
I've been working with js for like 5 years now, and I figured I could help some people out, if needed.
I wouldn't consider myself a js lord, but I have some decent experience, and even if I don't know something I'll be honest about it and at the very least I'm pretty sure I'll point you in the right direction.
I'm fond of vue, lodash, es6, node, eslint bla bla. I also know rails.
In any case, my objective with this is to learn myself.
So feel free to tag me if you have any type of question about anything js.
Cheers.11 -
No matter how many frameworks and supersets I try, I always conclude that nothing beats vanilla JS. ES6 in particular is such a beautiful language, and I love having fine control over what happens under the hood.
When I'm done I can just transpile it to whatever ES version, although it's slowly becoming a non-issue.2 -
I was just chatting with my dad. He used to be mostly a C# dev but changed jobs and is now doing mostly Java. He says he likes it better.... Because it doesn't have lambdas/anonymous functions.
Uh.... Java was the first and only language where you can define interface implementations in-line (aka a whole bunch of functions)...
And 1.8 supports lambdas for Interfaces that have a single function...
I bet he'll hate JS... Where functions are can be passed around like objects, ES6 now supports lambdas and await, async... and anonymous functions (apparently they're called arrow functions?)9 -
That moment when you go to your web development lab, write ES6 JS and your teacher tells you you are doing it wrong.
"That's not going to work in JS!"
You know something? SCREW YOU OLD MAN! 😕😠😑2 -
I wish homework worked like an ES6 Promise: "A Promise represents a value which may be available now, or in the future, or never."1
-
Trying to learn es6 JavaScript and Vue js, whilst also maintaining sites using jquery.
My head is about to explode... -
I'm actually making something for someone now. That means I have to make sure it works in IE. Which means no ES6. I die a little inside every time I type 'var'. 😫4
-
Best: learned a lot of new things: vueJS, ES6, Bootstrap, CSS3 transitions and transforms, use of some cool JS libraries...
Worst: an awesome web page turns a nightmare because of endless "upgrades" that the client wanted (I'm aiming to finish it soon)1 -
What I'm doing now, writing a JS library for a simple kitchen timer (like, something that can be wound up, is ticking, can be paused, etc). Here's a list of neat stuff I've learned:
Polyfilling as a lib author (I decided against it).
Packaging the lib (using Rollup, ES6 modules are totes cool).
Using flow to add static typing in strategic places (started appreciating types in JS since reading up on functional programming).
Modelling state and transitions using an explicit state machine. (Fucking finally. There's usually an implicit state machine somewhere, only spread out all over the app...)
Using mostly side-effect free methods, being very explicit about when and why things are mutated).
Test-first/TDD (ish) using Jest and the awesome Wallabyjs.
Freeing up mental capacity by letting Prettier format my code for me (it was hard to let go but totally worth it).
Started using git.
Did all work on Ubuntu after pretty much a lifetime of Windows (initially to separate work from gaming) and finally swapped MS Visual Studio for Atom.
When it's finished I'm going to publish it on GitHub, which will also be a first for me. Might try out some CI platform while I'm at it.
tl;dr: wrote some js, felt good2 -
I'm so fucking fed up with the npm ecosystem. Every single god damn time I've had to do anything it always takes DAYS to figure out how to get anything working and I always have to try multiple tools or libraries to final get it half way sorta.
I'm so fucking annoyed right now. They always turn out not that great, have lacking features or trivial oversights in functionality and ALWAYS have garbage documentation.
I just want to build a fucking npm library with TypeScript to be used with node. That's probably the NUMBER 1 use case so how fucking hard can that be?
So obviously I start out with tsc. That's quite simple, compiles all my stuff and shits out .js and .d.ts files. Okay so how do I use them via es6 import? I don't fucking know, because it doesn't work no matter what I do. The 'module' option in tsconfig is absolutely useless btw. It does *literally* fuck all. Nada. Absolutely nothing.
Okay I'm far from defeated, maybe I'll just have to bundle it. So I waste two days finding something that half works (I'm using fusebox right now) and at last I get a stupid es6 module as a single bundle... But what about type the declarations? They are nowhere to be seen and of course there's no option for that. Because Fusebox the pile of shit that's oh so well Typescript integrated apparently doesn't think TYPE DECLARATION FILES are needed. What the actual fuck.
And that's where I'm now. I need the fucking .d.ts files so I can use it as a module with import. Do I really need another fucking piece of shit tool that bundles these files? Honestly fuck all of this. "Oh the Javascript ecosystem is so great" YEAH fucking great, alright. Where 90% of the ESTABLISHED tools and libraries (we don't talk about the landfill of all the other shit) flat out don't do what you need. Again, how fucking hard can it be to make a npm lib with typescript? That should be NATIVELY SUPPORTED. If not by npm atleast by typescripts tsc.
FUCK NPM. FUCK JAVASCRIPT. AND FUCK THE WHOLE ECOSYSTEM4 -
The longer I work on front-end the more controversial my opinions become:
- Styling a button with display:flex is dumb.
- The DOM is not hard, unlike what the React team wants to have you believe.
- Specifying a <form> action matters, even if it's empty
- ES5 was the real JS revolution, ES6 mostly sugar-coated marketing
- Disciplined BEM (S)CSS is simple and flexible enough for most needs (vs CSS-in-JS, CSS modules)
- If editor support for Jsdoc were as advanced as Typescript, you wouldn't need the latter.
- There are cases where using floats and inline-block displays is better than the flex CSS box model12 -
(Ok, I love js in general (specially with es6), but here's something I hate about the "ecosystem". Dont take this too srsly also)
Holy fucking gagged shit, these project readmes that start out for too long about the project objective instead of stating the actual thing/s the software does.
WHAT DOES IT FUCKING DO!?
STOP BEING FUCKING FANCY ABOUT YOUR PROJECT.
Jesus christ, people jacking off about their awesome tool and how it will make everyone happy. No one cares.
"shitsmoke.js is a framework that focuses on delivering truly reliable data with static checking enabled on deployment."
WHAT THE SHIT DOES THAT MEAN?
Gimme a bullet point with the goddamn features (not the fucking BENEFITS) and I'm done.
These are like layers of marketing bullshit texts you have get through, getting more technical as you go on.
But sometimes they never do a technical summary, THEY GO STRAIGHT INTO THE GODDAMN API. And the API docs belong to a docs site, there is github.io and packages that take care of that.
You're like a goddamn linguistic detective, trying to disect the meaning of these words to understand if some package is what you're looking for.
And I don't wanna visit another website to understand what it does either!1 -
We support IE at work.
went to test page in IE, CRASH... With a freaking jquery exception, what?!?! Error was no help, debugging was pointless.
Took me 30min to find out that I can't define a variable in a JS function definition like "function doStuff(isThing = false)".... That's ES6 only...
Made sure I prevent further mistakes by setting my PHPstorm language setting to ES5.13 -
Unpopular opinion: JS isnt that bad (given you use ES6+). Only node needs to die, and if possible please yesterday.12

Hey. Can I borrow your ears for 5 minutes?
Since I've been out of school, I've often felt that even though I've learned how to code, the education went into a totally direction than the one I want to go. Of course a school can't teach you everything perfectly, but having almost no experience in frontend (mind you we learned the BAREST basics) just makes me feel entirely empty in that regard stepping up to a company. I've been pretty loaded during school, since I was struggling with a lot of things so I couldn't really find myself pursueing the direction of coding frontend apps being fun. I needed the little time I had to blow off steam playing games etc.
So the few things I know are all self taught, but I was never given a hand been shown best practices or solid advice where to look. Sitting down now at my pc trying to learn ReactJS for example feels incredibly draining and difficult, since we've never done JS in school ONCE. All the C# experience barely helps, since with ES6 being rolled out parallel to "normal" JS it's even harder to me to connect the lego blocks that is frontend development. Since many best practices are applied to ES6, I can barely even tell what previous practice they are replacing, making the entire picture even more spongy. In one sentence it's very overwhelming.
I've thought I'd apply maybe as a UX/UI Designer since I've got a great visual sense (confirmed countlessly by many, friends and strangers alike) maybe contributing to the frontend part that way. But as I was applying I've noticed that chances are seemingly pretty low to get accepted since it seems you've got zero reputition if you don't have a degree in Design.
It breaks me apart. I could probably apply as a frontend developer, but I am not sure if I would be happy doing that on the long run. Since just fucking around in Photoshop creating things seems like no effort and brings me joy, as compared to coding out lines for example.
I wanted to make money after school, improve on myself and my quality of life since I've drained that entirely for the sake of my education. Not spiral into another couple years just to eventually maybe get in the direction I want to.
On the flipside going into frontend dev with 0 skills, 0 experience, but being expected to have 2 years of hands on experience with the newest frameworks makes me feel empty and worthless.
I often hand out advice to other people on devRant, but this is the one time where I need some. Desperately. I feel shattered inside, getting out of bed in the morning has no incentive to me since I'll just feel like shit all day, watching YouTube to cheer me up temporarily, only to feel immense remorse not spending the day learning or improving on myself. Barely anything brings me joy. I don't wanna call myself depressive, but maybe I am just dodging the term and I am exactly that.
Thanks If you've read through this monstrosity of a rant/story. I'd be glad if you'd be so kind to give me a different take on my situation or a new perspective.
I am stepping on the spot and I am slowly dying inside because of it.
It dreads me to say it, but I need help.12 -
How would you go about writing ES6 in your node applications? I'm using nodemon together with babel-core/register and then using a shell script on my server to build it.10
-
There's plenty of literature about how to emulate classes and interfaces flawlessly in JS even without es6, but no, let's make a separate language using 20 extra keywords and several unnecessary concepts called TypeScript with its own compiler.10
-
Everytime I scroll through here I see people complaining about JS and frameworks being made for it. Well think about it, would you rather have to use old buggy JavaScript or help the community and the language achieve better standards? Just look at ES6 and ways to write code and JavaScript really isn't that bad. It's just misunderstood.3
-
So JavaScript/ES6 is kicking my ass. I'm not used to front end development as much. Idk when to use javascript and how. I dont know when I need to manipulate the DOM and how I do it. It's a new concept and I'm hoping PHP isnt gonna have as big of a learning curve..7
-
Use CoffeeScript they said, it will be fun they said.
NO! No, no, no, no!!!
Fuck this.
Converting old library written in coffescript to ES6 is just fucking insane.
I see 1000 lines of code to take me at least several hours if not a whole day.
and tests are yet to come. -
Fuck ES/TS 😐
Been trying for hours now to get ionic 2 to work with either generators or async functions. Doesn't work because async for ES 5 is only supported with TS 2.1 which breaks the angular compiler. Also can't use generators (not supported for es5 at all by TS).
Also can't really change the ionic build process to just take es6 output instead of es5 and transpile because it's a convoluted mess in a separate node module instead of just a gulp file like with ionic 1.x.
Why is the JS ecosystem such a fucking mess?3 -
I am a fresher in web development. I have already learnt to use nodejs, react, angular, vanilla js and made many projects. Majority of the work I feel is just CRUD based, sure there are some exciting things but they are only of a small percentage.
All that innovation HAPPENING is just glorified way of making a CRUD APP ONLY.
Oh mvc worked great on server side let's bring it to client side
OH mvc is such a mess, who thought about doing this.
Oh react redux is so revolutionary let's remake our app using it,,
Oh es6 fuck yeah, Babel, webpack sure, now my crud app is super performant.
Oh graphql, motherfucking cutting edge CRUD APP......
I need to know what's next, is there any breaking of this cycle11 -

Hey so this just came up and i have no idea how could i ddg this so ill just ask here.
I know you can use namespace{} in typescript but is there something similar in js (es6)? We are making a game and the variable names are getting scarce so it would be nice if we could like menu.offset or something. I know static variables in classes are a thing but im asking about namespace-y stuff here.3 -
Question: We are planning to transition our old ES5 codebase to modern ES6/ES7 and even typescript.
What would be the build tool you would recommend if we want to start supporting ES6/ES7 and even Typescript?
Webpack, Vite some other?
This is a vanilla Javascript Project with large codebase it's been built using custom build tools like UglifyJS and UglifyCSS and of after lots of begging it finally got the green light to move to a more modern build tool and start supporting a more standard JavaScript Features.
Mainly I want to move to TypeScript but transition would be slow so the build tool would need to support .ts and .js as well, that is traspile both the .ts and .js into one final production build.
What build tool would you recommend for that?8 -
Feeling the need to know everything about web dev (frontend for now) already yesterday, though not having a clue, what to look at first, as it's its own universe. Everything has a million ways of implementation, combination and features worth looking at.
Already have worked with basic HTML, CSS and JS, had a short look a Typescript, being confronted with React Typescript + Redux + thunk, SASS, learned some basics of all.
Feeling lack of motivation to build smth to learn, yet I want to explore. Afraid to get stuck in tutorial hell, although I know, changing smth here and there in the projects is a must for learning. Feeling the lack of understanding the bits and pieces of what can be styled with CSS in which way. Understanding how npm, webpack, the strange parts of JS, ES6, work.
So ... freaking ... much ....2 -
Front-end is basically staring at your creation for hours and have no idea what to add next to make it more complicated.1

Anyone know any good JS ES6 courses? Don't mind the price. It's great if it encourages practical learning :)

New employee joining the company next week. Where should she start on JS?
New employee is joining the company I work for next week, and I have the responsibility to teach, train and give her tasks. It is my first time training someone so I really have no idea how to do this. :P
She knows a little bit of Vanilla JS. Our projects are built with AngularJS (v1) with ES6, Webpack & Babel, ReactJS & jQuery. I want to put her on the project using AngularJS.
What order of learning do you recommend? VanillaJS, AngularJS & ES6? AngularJS & ES6? Or if you have any other suggestion, feel free to let me know.
Thank You.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 -
Peoples saying that JQuery dies after Document.querySelector is gone, but, write the functions like `slideUp` or anything that manipulates styles too, is very non-productive.
Do you know another lib (small) that makes these functions created by JQuery?15 -
GOD FUCKING DAMMIT I FUCKING HATE ES6 AND ITS GODDAMN IMPORT BULLSHIT
FUCK OFF AND LEMMIE REQUIRE MY FUCKING MODULES FOR FUCKS SAKE5 -
I just realized: People bitching about JS standard library, bundle size, need to use polyfills etc - is useless IMO. We need to start viewing transpilers as compilers and overall JS ecosystem like we are developing something in ActionScript Flash/Java Applet and exporting it for use inside browsers. And forget about "bad parts" of standard clean JS overall. See clean JS like it's as bad as it was in the past. (because without polyfills you still don't have most of the major es6 features in the IE browsers)
In the past we needed Flash plugins, Java plugins for applets, and they had size way larger than average JS bundle nowadays.

[ WEBDEV frontend QUESTION ]
I will need to build a new admin dashboard for representing a lot of data from the api. the API is written in PHP and this won't change. We are currently using jquery to make the data interactive (choose date ranges, different filters and so on). Were currently using morris.js for charts. I'm thinking this would be a good opportunity to learn and use a new js framework to make the data more easily bindable on buttons and selects (not so many listeners on buttons and shit like that).I will be developing the front end on my own, alone, so i mostly have freedom here. I need something that has implementations of chart rendering, and which I could learn in a week or two in the evenings after work (starting to work on this in the next week probably). What are your guys recommendation? Whats the best option for dashboards js wise? I was thinking vue, won't I shoot myself in the foot for using a new technology(for me anyway) right from the bat?2 -
So you need babel to run es6+ on node js because node js can't handle es6 yet. 🤔
Why can't the node guys work with the babel guys to integrate babel with node and save me the extra stress of having to figure out if my es6 code is not working because of a syntax error or because I didn't transpile properly🤷♂️17 -
tl;dr: What's the best tuto/course for learning webpack ?
I'm mostly a PHP dev, working on my own framework, but I also use more and more JS, and recently some Typescript (and loved it).
But my usual gulp workflow starts to grow old and limited. ES6 modules seems a great improvement while every webpack user seems to say it gives headaches. So what's the best way to start ? ^^4 -
Just about to go in to start a new contract on a greenfield project, using ES5. What is this, the fucking dark ages? I'm not even sure what isn't ES5 anymore...many fails ahead.2

TFW 'this' in functions loses its context when in promise chains and none of the blogs mentioned it :^)1

firstly, does anyone know of an online telegram or whatsapp group where i can ask silly stuff regarding web dev and get immediate answers, just like it is here?
secondly i am trying to learn js and there are just too many related terms that are messing with my brain:
"some features are supported ines5/es6/es15/es16/es17 , some are supported in chrome's v8/chakra/spidermonkey/android browser , some features are only supported in "serverside" and blocked in all browsers thanks to browser's vm environment; babel can't read this code, some features are provided only by node js..."
WHAT THE MESS IS THIS?
All i am trying to do is to write code that would make a website visible to everyone. if by specific browser , i want to target, chrome and its subsidaries and android chrome/other android browsers .
for other browsers am willing to make external converters later but don't want to change my code by 1 bit. And from what i know, each browser (at least the browsers am thinking of supporting) has the complete JS compilers already built in
can i or can i not built a complete functional website with those things?
and finally my main question : how to make custom exceptions in vanilla js? i saw this answer on stack overflow:
===================
function InvalidArgumentException(message) {
this.message = message;
// Use V8's native method if available, otherwise fallback
if ("captureStackTrace" in Error)
Error.captureStackTrace(this, InvalidArgumentException);
else
this.stack = (new Error()).stack;
}
InvalidArgumentException.prototype = Object.create(Error.prototype);
InvalidArgumentException.prototype.name = "InvalidArgumentException";
InvalidArgumentException.prototype.constructor = InvalidArgumentException;
Usage:
throw new InvalidArgumentException();
var err = new InvalidArgumentException("Not yet...");
=====================================
where is the error code? what would be the exception details? what is the line number/timestamp of error?why is that function making an error, i thought error/exception is a class in JS?4 -
Wtf is this ESP32 shit and it's hype?
I bought one because I thought JS on a microcontroller? That's gotta be fun!
I'm a hobbiest when it comes to MCUs and I do JS as a job, so I tought I'm made for this and I know at least as much as all the kids on the internet doing it.
Nothing makes sense with this shit. You have to flash wildly compiled modules of WHATEVERTHEFUCK with fucken python development-kits which have something to do with Lua to give you some kind of node-REPL which answers you with a bunch of strangely-looking errors starting with "stdin:x:".
If this NODE-MCU shit is made for JS why is there stuff about Lua everywhere you go with this, I don't get a single thing. Now I'm sitting on about 3 different git repos of sdks or what do I know and know less than before.
Oh and there is actually not a single tutorial really targetting the esp32. it's all about that 82xx-model.
Then I start googling around a bit more - It's not even ES6, it's just some ES3/5 shit. Why would you even do this. That's actually harder to manage than classic C/C++. You get no gain with it. Fuck me.
Wtf bro.23 -
Guys, I'm refactoring a server code from es5 to es6 and I would like to know how to get es6 errors like when I'm working with React. I have installed babel, and I can compile es6 code but I get errors that target the es5 (compiled) code so it's not easy to find the bug sources5

I really hate the hype with js frameworks. Every few months a new one appears F that F node.js and all the coffee es6 es5 bullshit. JavaScript should be like Latin. A dead language...3

Hey guys college student here. This easter I'll be focusing on learning JavaScript better. Yeah I've done some stuff with js, some small spa with angularjs (1.0), as well as some stuff in combination with a template engine ,(like thymeleaf). Should I start learning typescript along with angular 2/4 or es6?2
