Javascript could throw an error to alert you that the input is supposed to be a string, like most languages would do.

But you're calling a function specifically made for passing a string to an int... πŸ˜† There's gotta be some common sense somewhere here, guys.

Still, it's a very good point. JS should do this.

I would suspect one reason it doesn't do this is to be backwards compatible.

And god fucking forbid that common sense be in the language. Who the fuck needs a language with common sense, amirite?

Theoretically, Javascript is an untyped language, so there aren't supposed to really be static types. Giving type errors in this situation would be against design.

[–] jjjalljs@ttrpg.network 28 points 5 days ago (1 children)

Maybe the design is bad, then.

Lol you'll get no argument from me. It's not my favorite language.

JavaScript has types and it does have type errors, for instance

> null.foo
Uncaught TypeError: null has no properties

Please stop spouting nonsense on issues you know nothing about.

Dynamic types aren't static types my man. I think you got some learning to do.

[–] victorz@lemmy.world 5 points 5 days ago (1 children)

You did say untyped though.

[–] heavy@sh.itjust.works 0 points 5 days ago

Lol like facilitate versus effectuate

Theoretically, Javascript is an untyped language…

Function only handles string arguments correctly. Wat.
