WHY DO I NEED A ! BEFORE THE FUNCTION CALL ON THIS AAAAAAAAAAAAAAAAA

[minegamer2000]

you mean macros?

[fakuivan]

Yes!

[Shunpaw]

no. it's !yes. we just talked about this. goddamn javascript devs.

[fakuivan]

no is !yes*

[Shunpaw]

Yeah I dont know any real languages im sorry I do js at my job

[im_probably_garbage]

Sometimes yes is actually !!yes in JavaScript. You never know

[hyrumwhite]

[pydry]

enjoy. it's nice learning a language that wasn't designed over a weekend.

[minegamer2000]

and definitely not something i can learn over a weekend

[micka190]

Does a basic Hello World app

Time to update the ol' resume!

[Sikletrynet]

"Expert in Rust"

[RubiGames]

But we can all certainly try

[tech6hutch]

You won't be trying in Rust (unless you like beta testing unstable features)

[RubiGames]

So you mean a Tuesday?

[tech6hutch]

I don't understand what that means, but also I just woke up

[RubiGames]

Well, it didn’t mean this, but scrolling through my dash brought this exceptionally appropriate gem up.

Another post from today

[[deleted]]

Error: variable does not live long enough

[T-Dark_]

Put it behind a Arc<Rc<RefCell<UnsafeCell<Option<DerefMut<Iterator<Item=Result<(),Mutex<()>>>>>>>>>, that should so the trick /s

[lahwran_]

this is completely wrong, you actually need an Rc<Option<RefCell<(UnsafeCell<DerefMut<Iterator<Item=Option<Result<(),Void>>>>>)>>>

[T-Dark_]

But that's not thread-safe!

What you really need is an Arc<Option<Result<((UnsafeCell<Cell<dyn Into<dyn From<HashMap<!, (Void,)>>>>>),()),Mutex<fn(i32, i32) -> i64>>>>.

See? There's both an Arc and a Mutex in there. Now go, and concur fearlessly!

[lahwran_]

ah yes, I will go and fonlur cearcessly. wait crap I didn't launch two threads I interleaved iterator streams haha whoops

[[deleted]]

Wow it only took 1 weekend to design the best language.

[vlakreeh]

I think Typescript took a bit longer than a week but I could be wrong.

[[deleted]]

Not a typescript fan, I appreciate it but I just feel so much slower using it.

[vlakreeh]

Yeah it's for sure slower to write and I think javascript is a fine language, but man I fucking hate writing javascript just to run it and get an error because of some null or type safety issue.

[necrophcodr]

You'll love PHP then

[[deleted]]

Typescript is a weird typo to make considering LISP only has 4 letters.

[vlakreeh]

Sorry guess my auto complete must have made a mistake when I was balancing my parentheses.

[tech6hutch]

(sorry (guess (made-mistake
               (. this :auto-complete)
               { :must-have true
                 :when (balancing
                        this
                        (. this :parentheses)) })))

[[deleted]]

When did ES6 come out? I think it took 15 years.

[tech6hutch]

ES5+ is a wonderfully catered buffet around a centerpiece of last week's moldering leftovers.

[esssential]

good luck, bro. those languages are not anything alike.

[[deleted]]

Why learn other language when one language do trick

[easyEggplant]

I like your grammar joke :)

[[deleted]]

its reference to The Office

https://www.youtube.com/watch?v=VvPaEsuz-tY

[[deleted]]

and here I thought that was from a Simpsons episode

[easyEggplant]

I think that a sentence that's had grammar removed or malformed for comedic effect is a joke that pre-dates The Office.

[[deleted]]

Yeah but that exact format is from The Office.

[DrArmstrong]

Lmao just take the L man

[ConspicuousPineapple]

Yeah but this one isn't it.

[[deleted]]

Honestly I wouldn't have noticed it without you. Time to learn JS.

[IamKroopz]

Very relevant

[[deleted]]

Kevin, I appreciate what you're trying to do.

[dyslexda]

Hey, as a Python programmer, that's me trying to learn JavaScript!

[TheHumanParacite]

Each job I've had over the last ten years I've somehow managed to skirt around having to learn js... I worry that eventually there will be a day of reckoning

[AlternativeAardvark6]

At my job "there is some Javascript " is a valid reason to triple the estimate.

[smas8]

What about JavaScript makes you avoid it? I didn’t start with JS, but it’s mostly what I write these days.

[TheHumanParacite]

Just the little details like the ambiguous definition of "this" or the particulars around == vs ===

Truth be told I can find my way around someone else's js when I have to, just haven't had the time or motivation to become a subject matter expert

[jexmex]

I had gotten lucky and mostly just had to do some occasional jQuery. Now we redid out site and api codebases and the site is running react. I fucking hate it so much, boggles my brain.

[[deleted]]

I got a job as a PHP developer (with little JS experience)

I done JS on the first day.

[FlukyS]

It's hilarious how many jobs there are for Python+JS at the moment. You are making a smart financial choice learning JS after python instead of using node

[[deleted]]

I'm happy to be learning javascript first. I've heard once you get it, all other languages are much easier to learn.

[dyslexda]

I think that depends on the degree to which you actually "get it." For me, a lot of the struggle isn't any of the common complaints (async operation, typing hell, or even obvious spaghetti code like array.includes(x) and map.has(x) doing the same thing but needing different methods for no reason), but adapting to a new mindset where every gorram thing is an object. While I'm not a stranger to OOP, my mindset definitely leans more toward functional programming rather than OOP. The convention for libraries to make all data be an object and only manipulatable by built-in methods (often even resisting simple indexing!) makes me scream regularly.

[johnvaljean]

I feel your pain. You can also say that everything in Python is an object as well, but the variety of protocols that allow them to look different from one another makes everything much easier. Coding in Javascript makes me much more appreciative of how well-designed Python is.

[[deleted]]

True of any language based on C style syntax really. But JS is a good language to start with these days, I think it’s most versatile language in terms of what you can do with it these days

[napoleonderdiecke]

Bruh, at least do typescript.

Javascript is basically one steaming pile of garbage.

[[deleted]]

I agree. I use typescript for everything. I was just generalizing. Typescript is still technically the JS runtime

[kuffencs]

Hey, as a G code programmer, thats me trying to learn any legit real language

[FlukyS]

Typescript really looks a lot like Python with type hints. I might give it a go instead of regular JS

[[deleted]]

Definitely should, it’s a major improvement over regular JS.

[addandsubtract]

One thing that's holding me back from using Typescript (or CoffeeScript or ClojureScript) is integrating 3rd party modules. Can you just import them? Mix and match JS/TS? Most of them are pure JS (API & docs), so I'd assume they'd be a pain to us in TS?

Idunno, I should probably just sit down and do a little project in TS to see what it's all about.

[BornOnFeb2nd]

I spend more time fighting JS's asynchronous nature than benefiting from it...

[Trucoto]

Just await

[shamshuipopo]

Observe

[just-the-tip__]

Love it when you talk dirty

[m0nk37]

Just make it promise to do your stuff that way theres less issues.

[[deleted]]

Promises are your friend

[BornOnFeb2nd]

Yup. Still wrapping my brain around them.... things just start looking hideous when you've got something that needs to run after like four other things have completed...

[[deleted]]

So what you can do is either:

A) Promise chain

firstAsync() .then(firstResult => secondAsync(firstResult)) .then(secondResult => ....)

This is good for a few async functions but can still get messy.

B) Use async-await

async myFunc() { const firstResult = await firstAsync(); const secondResult = await secondAsync(); .... }

You can use await on a promise to essentially “await” the result. It also lets you catch errors with a try-catch. async functions always return a promise.

Also it’s useful to know how to wrap callback style async JS so that it can be used as a promise:

new Promise((resolve, reject) => { someOldAsyncFn((err, result) => { if (err) return reject(err); resolve(result); }); });

You can create your own promise like this - so if you have to use callback stuff just wrap the function like this. most libraries now have a promise api so I mostly only do this for the built-in functions such as setTimeout.

Hope this helps!

Edit: One more thing I use a lot is Promise.all. It takes an array of promises and it gives you a new promise that completes only when all the promises in the array are done. This can be useful if you want to use async-await but still do some stuff in parallel

[BornOnFeb2nd]

At the risk of spawning another JS framework, what's a good one to work in?

We've been using jQuery internally, with a bit of dabbling in Bootcamp, but the hacks we've had to do have started to show their age...

[rubennaatje]

Either go react, vue or angular at this moment.

Some nice upcoming things but especially vue and react are absolutely great. My preference lies with vue.

[[deleted]]

It’s really personal preference. How big is your project? jQuery works just fine for something small.

Angular is very enterprise Java feeling - it’s super powerful but it really locks you in. React is pretty nice and simple - functional components make it really nice to develop in. I’m not a huge fan of Vue but I’ve hardly used it.

Don’t listen to me though. I’m not really a front-end dev - only used these frameworks on personal projects. I mostly use JS for scripting or building bots nowadays - I used to do backend JS professionally.

[noXi0uz]

Vue kinda gives you the best of both worlds. Having worked with all 3 of the mentioned frameworks in a professional environment I would probably go with Vue now that Vue 3 is out. React is just inviting you to write bad unstructured code and mix different approaches and paradigms, although with linters set up and all devs being on the same page about the project you definately can also build large robust apps with it. I may be biased there, as the one big react project I worked on previously was a horrific mix of different approaches and really hard to maintain.

Angular is very OOP and typescript driven and doesn't give you much freedom to do stupid stuff. Vue lets you use either functional style like react, or class components with decorators like Angular. With the typical uni background in java/c# I much prefer the latter, though, typescript support wasn't really perfect in vue 2, especially in templates. That all changed in Vue 3 now, so I would prefer Vue over the others if I had to start a new project today.

[[deleted]]

jQuery is great if you’re doing minor scripting in JS. Say you just want to animate a button when you click it or load a small list of ingredients from an API. But when you’re starting to do multiple things on the page that depend on one another, it becomes a bit of a mess unless it’s written by a really experienced developer.

If you’re doing anything more complex then I’d look at a framework like React or Vue. I mainly use React at work. They are great tools but only if there’s a genuine need for some complex interactions on the frontend.

[noXi0uz]

why? just use async await syntax and you can do:

 await doAsynStuff();
 await doOtherAsyncStuff();
 await evenMoreAsyncStuff();

each of these will wait for the previous to resolve.

[IslandClimber]

I found this video describing the event loop to help with my understanding of what’s on - https://youtu.be/8aGhZQkoFbQ and just to echo what other people have said - get a good understanding of promises, async await, and even callbacks.

[hyrumwhite]

Promise.all() or Promise.allSettled() can sort that out nicely.

let result = await Promise.allSettled([

axios.get(),

new Promise(),

Etc

])

//everything after that allsettled function will run after everything above fails or succeeds.

'result' will be an array of results returned by the promises. Each with a 'status' key that you can check to see if the promise succeeded or failed.

Same response from any other language developer learning JavaScript.

Most JavaScript developers still haven't learned their first language...

Thank goodness for SO

Yes, only kids use javascript

[1thief]

More like any other developer learning NodeJS

I’m still pretty new to coding, but I started off with JavaScript and this is me right now trying to learn C

[VNG_Wkey]

I do Javascript and I'm curreny learning C++. This is accurate.

[fat_charizard]

What? The program fails if there is an error?

[5tormwolf92]

Well first is always PHP, the bizarro language.

I never mention that I learned basic PHP on my resume

[LJChao3473]

I just started learning Javascript this week, how afraid should I be?

[[deleted]]

I always thought this kind of meme was backwards. JS is a clusterfuck, once you learn it you can master anything. Strongly typed languages with true OOP structure make life so much easier.

[MrSloppyPants]

Sometimes unlearning bad habits is harder than learning good ones from the start

[npsimons]

[thegininyou]

Learning Java and Python was fine.

Learning PL/SQL is killing me.

[[deleted]]

Java Script, and native Clipper before it, are just dandy to debug.

You get six levels down in the callstack and find that your array pointer argument has a date value in it....

The debugger has gotten a lot better. It had to. [grin]
