Typescript-基类继承

Question

我正在尝试了解此旧代码。我了解接口，类是什么，但不了解为什么要从new (this.constructor as any)(this)函数返回clone？你有什么想法吗？

interface IClonable<T> {
  clone(): T
}

export interface IBaseComponent<T> extends IClonable<T> { }

export interface IBaseComponentParams { }

export class BaseComponent<T> implements IBaseComponent<T> {
  constructor(_: IBaseComponentParams) { }

  clone(): T {
    return new (this.constructor as any)(this)
  }
}
