💻 Code

function f() {}

(function () {
	f.apply(null, arguments);
}());

🙁 Actual behavior

arguments errors with Argument of type 'IArguments' is not assignable to parameter of type '[]'.(2345)

🙂 Expected behavior

No error.

Additional information about the issue

f.apply(null, arguments) is a universal idiom for decades, albeit one that's fallen out of favor in lieu of f(...arguments) - and when one needs to set the receiver, f.apply(O, arguments) is the only choice.

Somewhat related to #68307; basically, there should probably be an "arraylike" type that all of arrays and arguments and strings and nodelists can assign to.

Start with the TypeScript Playground link and reproduce the error in the shown function and apply call. Read the discussion, including related issue #68307, then determine how arguments-like values should be accepted while preserving type checking; done means the example compiles without the TS2345 error.
