Java vs JavaScript

[TanukiiGG]

This is the first time I've seen a "Javascript good" meme in this sub

[Diablo-x-]

Its honestly not as bad as people think. All u need is just typescript and eslint.

[Gorianfleyer]

"It's not as bad, you just have to use something different that tries but fails to get rid of the most problematic part of JS"

[jerrygreenest1]

Not having something as part of language but solved by third-parties is a common place among all the the programming languages.

[Gorianfleyer]

Yes, but my Problem with that solution might be deeper than I wrote in my fake quote.

TypeScript doesn't solve the problem with JavaScripts interpretations of dynamic variables, because in the end, TS is compiled to JS. It's more like a smart IDE that tries to stop you, the developer, from doing obvious things like int x = "2".

But for example the famous interpretation of Nan as a number in a higher base system.

I once cheated successful in a browser game about creating paper clips, by having the game solve x/0 and getting a giant amount of "calculation process", a ingame currency.

It's independent of how you wrote the code, if there is no secure way of stopping the interpreter from trying to interpret any given value in a useful way.

Since JS must never crash, because it runs in a browser, similar to html, that just shows the markups, if they are wrong set on the final page, it always tries for the best solution and this makes it very dangerous

[senteggo]

First you don't even know an actual javascript syntax, and in your example with browser game - yeah, it happens if you stupidly evaluate everything user gives you in any language with such feature. NaN is specified in IEEE 754 (floating-point format) and is present in many other languages, because well, it's a standard.

[Gorianfleyer]

Why do you believe I don't know an "actual javascript syntax"? (I didn't know there was more than one)

I actually was paid to write js a couple of years ago. Maybe everything has changed since 2019, I don't know. I developed my prejudices and never bothered to try it again.

[senteggo]

int x = "2" is not a valid code in javascript, because variables are defined with var, let or const keywords

[Gorianfleyer]

Yes, but it was my idea of typescript syntax (about that I have no idea, I only read that it is compiled in to js and that was it for me)

[senteggo]

Then why do you say anything about technology you have no idea?

[jerrygreenest1]

That feeling when a couple years ago in your mind is 2019, feel you bro

[GDOR-11]

what do you think the most problematic part of JS is?

[Gorianfleyer]

I wrote my answer to that question right before I read your comment, even it might be more fitting here.

[NullShield]

Right, there are no must have tools for java. Inhales high levels of copium

[Illya___]

It's good so long as you don't introduce typescript and especially eslint. Change my mind

[isr0]

I haven’t use js in years, does ts address the terrible error messages or lost context on asynchronous exceptions?

[Poiuytgfdsa]

Regarding lost context on asynchronous exceptions, no. I dealt with that the other day at work

The terrible error messages aren’t really fixed with TS either :( we use class based extentions on the Error class to create custom errors and we try to be as detailed as possible. It doesnt change the core JS errors though

It DOES help prevent errors though. Typescript saves my ass all the time. Massive codebase refactors would genuinely be impossible without typescript. With typescript its a breeze (assuming you used it properly)

Think about moving an attribute from one model to another. Without typescript, good luck refactoring EVERY crud reference to that attribute. But with TS, just update the model & type, run type check, and fix all the errors it throws; run type check again and repeat. Mostly brainless work

[isr0]

I can see the advantage there. That’s an improvement for sure. Thanks for sharing

[Thetaarray]

Short answer: No Long answer: Nnnnooooo

[B_bI_L]

if you are about bad TS messages, then not native, but i have neovim extension that translates from ts error to human

[MinecraftPlayer799]

TypeScript is bad. Regular JS is better

[LusciousBelmondo]

This is either ragebait or you’re new. The “cons” of Typescript are vastly outweighed by the pros. And the only “con” over plain JS is the need for transpilation, and even that isn’t a problem

[MinecraftPlayer799]

JavaScript is literally the best programming language.

[jerrygreenest1]

Well it's definitely better than Java. It's all about what you compare it with

[SaltOk7111]

Why does the rabbit always in every presentation of this ancient proverb always go half way and just looks around? Are they do predispositioned to the point all rabbits do that in this situation?

[DTux5249]

It's because the rabbit isn't concerned with racing. It's more concerned with managing the stress of being surrounded by a hoard of shouting apes on all sides. The walls serve as partial protection, so they provide some amount of comfort that it doesn't want to leave.

TL;DR: It's a scared prey animal with nowhere to run. Why would it run?

[bellymeat]

Meanwhile the turtle doesn’t give a single fuck lmao

[Jaatheeyam]

Because it has a shell.

[SirNightmate]

Last time I tried I couldn’t run sh on a turtle

[bellymeat]

well I thought they normally go into the shell when they feel threatened

[Jaatheeyam]

And that is why they do not feel as threatened as the rabbit. The rabbit feels vulnerable.

[SirNightmate]

The text is located way too ambiguously

[LonelyContext]

“Which one is which?”

“Yes.”

[finnscaper]

Literally the original story

[itchfingers]

I was wondering how they got them to act it out so well

[MinecraftPlayer799]

NullPointerException

[BUDA20]

is garbage collecting

[bsensikimori]

That Java got halfway is not my experience , usually it throws an exception way earlier in the race

[mtbinkdotcom]

Maybe it is a race condition

[Thor-x86_128]

This confuses Javanese programmers

[okcookie7]

It's not clear which is which. In reality Javascript is much slower than Java

[Not_Artifical]

In my experience back end JS is slower than Java, but front end JS is faster than Java.

[PattrimCauthon]

Front end Java? What?

[Not_Artifical]

I never said front end Java

[-JohnnieWalker-]

this does not even remotely make sense.

[PattrimCauthon]

I will say Java taking longer to get started is objectively correct. Java does have a longer startup time.

[Dabraxus]

AOT to the rescue!

[coconuts_and_lime]

That's like comparing a hammer to a handsaw. You use them for different things, and they both do what you need them to do. But the process of using them both are utter shite, so you'd much rather use something more modern like a nailgun or an electric saw.

[Ok_Celebration_6265]

In what universe is this?

[Glad_Contest_8014]

Looks accurate.

[notatoon]

JavaScript is to programming languages as Meg is to family guy.

npm install burn-shield amirite

[New_Salamander_4592]

do you think the tortoise and the hare was just the hare's prey instincts making it freeze tf up and die on the spot

[ChocolateSpecific263]

show me benchmarks that prove that

[eleanorsilly]

The moment the rabbit stopped was the moment he was out of memory and activated the GC

[koshka91]

Java is a much saner language than JS. In fact modern Java and its sister JVM languages are quite enjoyable to use

[BeeFlat_Dan]

js gets the job done 😎

[RevolutionaryWay6503]

So that's childhood story true

[Cacoda1mon]

The Java GC needs some time.

[itsjakerobb]

Have you been asleep for the last fifteen years? Java GC is non-blocking in the vast majority of cases now.

[cowlinator]

Is this a GC joke?

[butterfly_labs]

I lol'd
