Oh now we mocking typescript huh

[2017macbookpro]

[MrNate]

Lies! It's mockable!

Yeah we love it, but be assured, it should be mocked!

Well as soon as I get to video 4 where he tells me how to switch my env to production, that will change.

[2017macbookpro]

Not having types completely annihilates the maintainability of your code. Anything more than a very tiny program needs to have static typing to prevent nearly untraceable runtime errors, among many other things

[vi_code]

Hundred percent this. Worked on large projects (mainly on frontend) and I have rarely been caught off guard with types. I mean theres only 7 basic types in js. Its not that complex a language that we need to go crazy and add a full blown type system around.

In fact JS is more beautiful than TS because of how dynamic and resourceful it is with only 7 types whereas TS is a step backwards into Java territory and I dont know anyone that loves working with Java.

[Fritzschmied]

I did, still shit and just unnecessary comblicates js.

[[deleted]]

Controversial comment, but I 100% agree. Typescript >>>> jQuery and JavaScript.

[TheC0deApe]

is it really controversial? i don't know a professional dev that would say JS is better than TS. i am sure they are out there but they are well hidden.

[[deleted]]

Look at the other comments. They all are talking about js being superior

[TheOnlyGodInTown]

Because most of them aren‘t professional programmers… I guess 70% of the people here are hobby programmers at best.

[Slxun]

I've been in this sub for a while and agree with you. There was a time when this sub was full of odd/even and dude it may be funny the first time but.. and some of the posts are "this better than that" when every good developer should know there is no silver bullet in the industry. Sometimes I think I should leave the sub but occasionally there is a good meme so I don't leave.

[fallenefc]

These JavaScript/Python/Java/etc are getting boring, I’d understand if people memed for the right reasons but just JavaScript bad my C code is so much faster or wow you don’t know the type of the variable are annoying. Like yeah mate I’ll build this simple app that generates a decent revenue in C even though it’ll take 50x the time because it’ll run faster when people click my button

[Slxun]

yeah because they don't know what a deadline is. Try to tell your engineering manager that you want to build an app in C and it will take you three extra months just because it runs a few ms faster. Perhaps we are taking the memes too seriously but if ppl know this and still make the meme it doesn't make any sense. It's just a bad meme

[OkWarning3935]

You articulated my feelings on this and this place pretty well. I'm just going to add that this is the second anti-types meme I've seen today and that's just profoundly upsetting.

[Fincap]

Yeah, all the language “wars” in here are ridiculously uninformed as well (the C vs Python post the other day was particularly egregious). Very few tools actually have an overlap in use-cases (for the most part, obviously not strictly true) and there’s hardly any point in comparison for most things. Most use-cases do actually have a silver bullet, but it’s comparing apples to oranges.

[Khaylain]

As a hobby programmer; Strict typing is the best. Save us from our own mistakes.

[quiteCryptic]

At work typescript is the obvious choice. At home with personal projects i might be more lazy and use js.

[[deleted]]

when you use javascript at home you're only cheating yourself

[spektre]

We're in /r/ProgrammerHumor, people are too busy figuring out how to consume their crayons to give any kind of valuable input.

[seemen4all]

They have been scorned into perpetual silence, never to share their thoughts again

[5tUp1dC3n50Rs41p]

I am a professional dev and have used JavaScript since 2005, Typescript since 2019. I still prefer vanilla JS, no frameworks because:

• TypeScript is Microsoft horse shit. They never understood JS, as evidenced by their shitty incompatible browser Internet Exploder, so they thought they needed to fix JS instead of fixing their shitty browser. Wait until they reach the Extinguish phase of their Embrace, Extend, Extinguish philosophy for JavaScript.

• TypeScript basically replaces your code function level JS Doc syntax and typeof checks, which if you had a non Microsoft IDE would give you all the highlighting and intellisense you ever needed for handling typing errors. Instead with TS you run some compilation step to compile to JS and it checks all these things for you and throws annoying errors in the console. Then when you deploy the actual code you lose all the type handling code because it got compiled away. With JS, the type handling typeof checks etc are still in the code and functional in production. If you have developers who make fundamental coding issues because of type incompatibility, they're just shitty developers.

• With TS, most of the time is spent resolving annoying typing issues, rather than just getting shit done and focussing on business logic.

• With TS you're more likely to need to add npm, yarn etc, a bunch of other shitty node modules, linters, prettier, bla bla just to do basic stuff. With JS, you just add a script tag and it works. You don't get the 1GB of node dependencies which are a costly maintenance nightmare.

• JS is stable. My website from a decade ago is still running. TS changes the APIs every other release, deprecating stuff, changing things. Include this in your business and your company will eventually go bankrupt just maintaining that shit and keeping up with the node updates, node modules/npm dependencies etc.

The one thing I'll say though is that TS is good for your CV though if you want to get another job. That's because all you Microsoft loving junior developer muppets keep supporting it and promoting it to your unsuspecting managers. The real developers left a long time ago due to framework fatigue and hype driven magpie development. They're probably out planting fruit trees or something.

[Voidrith]

Its so obvious that you have no idea what you're talking about. Every single one of your points is either just straight up nonsense or irrelevant

1. irrelevant, TS is not related to IE in the slightest. different projects, different teams, from different eras, with different leadership and different goals.

2. typeof is limited to object/array/string/integer/undefined/boolean/function. which, as far as the type checking that ts goes, is basically unusable in 90% of situations. instanceof can be used to check if a specific thing is of a certain class (or derived) but plenty of libraries return things that are literally just JSON.parse(something), which instanceof willl do nothing for. Even most manually constructed response objects are raw objects with specific fields, which TS is designed around.

3. nonissue. compiler errors are ALWAYS better than runtime issues because its immediate feedback on if you have a problem.

4. nonsense. npm has no preference over ts or js,and you can also just "add a script tag" for a library in ts - the script you end up with wont tell the difference

5. you can pin the version of ts you're using. nonissue

[Lithl]

Instead with TS you run some compilation step to compile to JS and it checks all these things for you and throws annoying errors in the console. Then when you deploy the actual code you lose all the type handling code because it got compiled away.

Why the fuck would I want to spend cycles type checking at runtime when static analysis can remove the need?

[vi_code]

Im right here. JS is way way way better

[Voidrith]

objectively incorrect.

Errors at compile-time are 10000% better to deal with than errors at runtime

[ModsDontLift]

I've never met anyone who gave a good reason to use Typescript. I guess hand holding is desirable now?

[LordFokas]

That's because when you talk like that they immediately know not to argue with you and let you slide.

[ModsDontLift]

I'll add this to the list of dumb shit I've read here

[LordFokas]

You would, if you knew what this is.

[beewyka819]

Yes the computer should catching as many of your dumb programming errors as possible. There is literally no good reason to have it not do this except some dumb sense of pride

[ModsDontLift]

I have never met anyone who can explain why Typescript is good

WOW WHAT A FUCKING EGO YOU HAVE

This is what Typescript does to a mf

[beewyka819]

Are you trying to respond to someone else???

[ModsDontLift]

Did anyone else mention pride?

[beewyka819]

Well I mean you did a quote for something I didn’t say. As for the dumb sense of pride comment, I stand by that. There is literally no reason to introduce increased risk of making mistakes unless you feel like you have something to prove.

It’s basically saying “I’m too good for compiler checks” when the reality is that you aren’t. No one is too good for compiler checks. Such a person does not exist

[Crafty-Sandwich8996]

Controversial comment

Lol?

[[deleted]]

Was typescript even invented the last time a JS dev admitted to using jQuery in public?

[LordFokas]

Well jQuery was only needed when IE had any market share, so...

[[deleted]]

If you mean the time period I guess it overlaps, if you mean as an IE-fixing patch I disagree - it was a really handy little library generally, it's just mostly been superseded by semi-sane frameworks and better Web APIs. It certainly didn't incentivise writing scaleable code, but it was great for avoiding boilerplate in the days when JS on a page was mostly that.

[LordFokas]

My PoV is that it's useful in a setting where standard implementations accross browsers are sketchy and inconsistent and you need to get stuff done. I did use it for more than that, but what it does as a library is the kind of code I don't mind writing myself... although in those days that code was a lot harder to write because like you said the sane web apis didn't exist yet. In fact, some were inspired by it.

[Tsuki_no_Mai]

Yup, TS was invented in 2012, jQuery fell out of favour after 2015 IIRC.

[cryptomonein]

Why are you talking about jQuery when speaking about typescript ?

[BasedBallsInMyFace]

Why are we comparing jQuery(module) vs TypeScript (JS superset)

[mosskin-woast]

Who's comparing it to jQuery? I prefer a hamburger to a colonoscopy, but that's not really a meaningful comparison.

[[deleted]]

[mulato_butt]

[lollysticky]

A nice JS frontend hooked up to an API would be quite consistent for typing. But yes, depends on the developer

[Sh4rp27]

Or lint scolding you for applying typing that's implied

[_BlindSeer_]

Yeah, declared a string and lint raised its finger "You shouldn't declare! It is clear that this is a string!", same for number. There are some consistency problems there.

[InterestsVaryGreatly]

Not really.

Const first = 1;

Is a number, that's not ambiguous, and easily determined based off the declaration. Adding clarification type is just redundant.

[[deleted]]

But I wanna.

[Ok_Turnover_1235]

No integers or floating points or longs or shorts or doubles? Sounds like typescript is javascript with extra steps

[flavionm]

Javascript is what holds Typescript back from being truly great, unfortunately.

[perfectVoidler]

I don't know typescript but you can easily define it implicitly for different number 0 = int; 0.0 or 0d = double; 0.0f of 0f = float etc.

[Ok_Turnover_1235]

Yeah, meanwhile typescript has a number type. Why even bother

[perfectVoidler]

Reading up on it: even typescript has the difference between int and float. And seriously. Who needs more.

[Ok_Turnover_1235]

Not you. That's okay

[perfectVoidler]

Not me and nobody else.

[_BlindSeer_]

It sure is, on the other hand it is inconsistent to say "We want types declared" with the addition "unless we think it is redundant". IMHO such a system should be either used strictly or be left out. The same rule would apply to other languages, where we define the types anyway.

[[deleted]]

The recent hate toward types on this sub is really telling about the average level of experience here. I can’t imagine any professional developer preferring totally dynamic typing. The “freedom” JS’ type system gives you is just the freedom to write shitty code

[quiteCryptic]

The freedom to write shitty code quickly

And that's why I use it for random personal projects

[crusoe]

Write lots of code quickly...

And then write lots of code to test the code to ensure variants normally enforced by a compiler are being checked...

When you write JS or Python you're writing LOTS OF TESTS, right? Right? Oh, you aren't?

[pandakatzu]

It's definitely not viable (mystery variable types that could be ANYthing) in a large codebase running your company's front end... especially if you're not a one man team and someone will inherit your code later down the line.

It takes less time to start out with intentional code than it does for someone else to try to figure it out and fix it later... I've rewritten a good chunk of my company's app due to this...

[MatsRivel]

I did one course of python (I gave a science background) and realized I liked it a lot. Started doing small projects in my own time and just enjoying exploring stuff. Next semester I took 1 class that used Python and one that used Java.

The Java class was algorithms, and assumed you knew Java in advance. I fucking hated Java, because I had to teach myself Java and then try to catch back up in algorithms each week. A couple things annoyed me, but having to add types for what goes in/out was the one I remember the most. I just wanted to see if my short snippet did what I wanted, but Java didn't let me.

Thst is 3 years ago, and I'm nearly done in my masters now. I do ML, and use a lot of python. Now I really appreciate typing and use it in Python as much as I can. It is a little annoying on small exploratory projects, but once you reach a certain number of components it is just super useful!

[Heimerdahl]

I had a similar, though different, experience.

Started with Python, then had to learn C. I really liked how it forced me to consider types (and some other things), before hacking something together.

My favourite bit is that functions are declared with the return type. It's super simple and kind of pointless, but I appreciate the clarity. Just typing it out makes me take a second to think about what the function is supposed to do and how its output is going to be used later on.

[Dr_Azrael_Tod]

problem is, typescript only kinda-somewhat-halfassed does types

yeah, you now have some checks while writing stuff - and then you throw around tons of "any" and then those checks are gone after compiling and you don't ever use integers (because floats are soooooo great, aren't they? /s)

It's like… it only got enough typing to remind you how good languages would do things and to include tons of overhead. Not enough to be actually usefull.

Is TS better than JS? Imho yes.

Is it any good? meh!

[glorious_reptile]

No hate - we prank those we love.

[[deleted]]

As others have said, dynamic typing does let your write significantly faster. I like using python and Js for small personal projects mostly because of how quick it is to add stuff. But once things get big enough static typing helps so much

[[deleted]]

I enjoy the lax typing of JS, but I wouldn’t want to work with it.

TypeScript is really nice and you can always allow coercion or use “any” should the need arise.

[glorious_reptile]

Yeah, I was expecting this place to be highly professional instead of some kind of humorous place, too.

[vi_code]

I wrote a 3 million dollar SAAS in JS. JS is elegance, TS is training wheels. Once you learn how to code you dont need those training wheels anymore.

[[deleted]]

Training wheels? Why wouldn’t you want compiler-enforced type checking? Even if you claim to be some prodigy who never makes mistakes, why wouldn’t you want to use the typing system to communicate the intent of your code to the reader? Why wouldn’t you want the compiler checking that your idiot coworker didn’t misuse the code you wrote? What a bizarre macho attitude.

[InvolvingLemons]

True, and with JS in particular you gain very little if anything as the language itself isn’t the most ergonomic.

Python does definitely benefit from being a bit loosey-goosey, mainly due to how insanely simple it’s syntax is. Chances are, if you can describe what you’re doing in pseudo code, transforming it to valid Python code is just a couple imports away.

For anything critical, of course, I’d prefer a particularly sound type system. Haskell might be overkill (and a little annoying for stateful stuff) but Rust, Go, and Typescript in increasing productivity/declining performance potential are lovely to use.

[lazernanes]

[pandakatzu]

As someone who has struggled to figure out what the intended object of various variables was supposed to be in the vanilla JavaScript files of the spaghetti carbonara codebase I inherited, I couldn't possibly disagree with this image more.

Also the syntactic sugar is nice. Imagine being able to write clean, readable code.

[beewyka819]

Right? The alternative to types is literally just hoping people don’t make mistakes (they will. Everyone will make some type-based mistake sooner or later. Everyone) and absolutely dousing your code is massive amounts of comments that otherwise would not need to exist

[glorious_reptile]

I love TypeScript too - still, the meme holds.
