ES6 类：是否可以从父类访问子类的构造函数？

Question

Using ES6 class syntax, is it possible to create a new instance of the current class from the parent? For example:

class Base {
    withFoo() {
        return new self({ foo: true });
    }
}

class Child extends Base {}

(new Child()).withFoo();

I'm looking for something similar to PHP's new self() syntax.

您可以通过this.constructor访问当前实例的构造函数。
