打字稿类参考

Question

Flow的概念是，您可以编写以下类型定义来引用从另一个类继承的类： function getHouseClass(): Class<House> {}

这是指类，而不是类的实例。

Typescript中有类似的概念吗？ Class<House>显然在TS中不起作用。

谢谢！

I think @toskv is correct. If you look at this comparison between the two (below 'Accessing the type of a Class' headline):

Flow

class Test {};
type TestType = Class<Test>;
// This should be equivalent to (if you can confirm, please send a PR):
type TestType = typeof Test;

TypeScript

class Test {};
type TestType = typeof Test;

The following should then be the same:

function getHouseClass(): typeof House { return House; }
