在打字稿类型数组 - 就是数组℃之间的差异;美孚＆GT;与富[]？ [英] Typed arrays in TypeScript - what is the difference between Array<Foo> and Foo[]?

问题描述

在打字稿我有一个类富

class Foo {}

我想富的实例数组。之间有什么

I want array of instances of Foo. What is the difference between

var foos : Array<Foo>;

和

var foos : Foo[];

在我看来，这两个定义给定类型的实例数组，有什么不同呢？

It seems to me that both define array of instances of given type, is there any difference at all?

编辑：什么是这些结构的名字？我如何正确地指给他们吗？

What are the names of these constructs? How do I correctly refer to them?

推荐答案

They are both identical as type annotations, so you can use whichever you prefer.

由于添加泛型数​​组语法只提供了。

The Array syntax has only been available since generics were added.
