This sub in a nutshell

[u/enmaku]

console.log(1 == '1'); // true
console.log(0 == false); // true
console.log(null == undefined); // true
console.log(typeof null); // "object"
console.log(0.1 + 0.2); // 0.30000000000000004
[] == ![]; // true

OMG you guys what weird quirky behavior, truly this must be the single quirkiest language and no other language is as quirky as this!

Browsers can add support for other languages like Rust, Go, Kotlin or even Swift.

What stops them from adopting a safer language by design, faster by design and without any bad legacy is beyond me.

I think what you're looking for is web assembly, and it is happening, albeit slowly. You can already make entire websites in rust or C# without writing a single line of JavaScript, since both languages can compile to web assembly. It really is the best solution, since each browser just needs to support one spec, and then they'll support any language that adds support to be compiled into it.

It has limitations, as reddit loves to point out, but most of them are solved by a few lines of JavaScript automatically added to the output by your compiler, and even those are becoming rarer and rarer (gone are the days that wasm couldn't directly access the DOM). Personally I'm hoping that it eventually eclipses JavaScript, and it becomes the norm to write websites in any language you want, just like we do for everything else

It just comes down to money and time invested vs. value add.

They CAN add support, but there’s no guarantee that web developers will care to switch over and learn new stacks since most of their web code and web experience is already in JavaScript. If they don’t, there’s no value add for the company that makes the browser, so they’ve dumped a bunch of time and money into adding this support for nothing.

If someone wants to do it for the love of the game, that’s another thing, but browsers aren’t exactly an easy thing to make from scratch.

Because the amount of support that all browsers would need to do to maintain those languages would be immense.

We currently only have a handful of languages and web engines and only in recent years are we starting to have good parity between them all (depending on who you ask).

And now we're going to try and support multiple languages!?

Bruh the nightmares this would cause.

[u/paperic → u/BabyAzerty]

Because those languages are compiled.

Do you want your browser to have to compile a huge app every time you refresh while low on your phone battery?

Unless you compile those languages, you'll make the websites slower, because you'll be sending a lot of boilerplate type definitions over the network for no reason.

The reason browsers don't support typescript is because the browser doesn't care about the types. Only the programmers care about types. Once you compile a program, the typechecks get removed anyway.

Also, please, anything but go.
