Type Script: Array<Object> vs Object[]

Question

In Typescript what is the difference between these assignments:

var Object[];
var Array<Object>

Does generics in Type Script has the same semantic meaning as in languages like Java or is it simply syntactic sugar?

It's just sugar. Object[] and Array<Object> are exactly the same in TypeScript.

One way to check this is to write this code:

var x: Object[];
var x: Array<Object>;

Duplicate variable declarations must have exactly the same type, so the lack of error here implies that the types are identical.
