typescript 里面，如何声明类型为某个类的实例?
class Helper {
title = ''
static create() {
return new this
}
}
class A extends Helper {
name = ''
}
访问 A.create().name 会报错。

Using Class Types in Generics
When creating factories in TypeScript using generics, it is necessary to refer to class types by their constructor functions. For example,
function create<T>(c: {new(): T; }): T {
return new c();
}
