Typescript2: Array<any> and Array<Object> difference

Question

Which is the difference between declaring a field as Array<any> and Array<Object>.

Is there some extra collection tools in typescript?

Answer 1

An Object in TypeScript is the same thing as in JavaScript.

The difference is that any accepts primitives as well: a number is not an object, unless boxed to a Number.

So while an Array<any> can contain primitives, an Array<Object> can't.

TL;DR: don't use Object.
