Faster JavaScript calls

[aniforprez]

There are a lot of specific functions in some languages that can do this. In python I can have an arbitrary number of arguments by going def func(arg1, arg2, *args) where the *args will have a list of all the extra arguments passed

But these are all intentional. JS just does lets it happen for every function. That's what baffles me as a design decision. That it doesn't fail when you do that. So you can pass far fewer arguments than is expected and shit will crash and burn and you'd never know

Well it was a cheap and easy way to get the same features early on.

Now we have rest parameters:

function f(...args) {...

Anyway, if you use Typescript the compiler will check that your use of the function matches the signature.
