I dunno, as someone without much experience with Javascript, it is a little odd that arrays return the index alongside the value by default.

It has little to do with the type system. Variadic arguments can be typed given a type system that supports it.

arrays don't do that, but map() does. Normally in js you can just ignore arguments you don't care about, but it does lead to surprises like this one.
