装饰者模式(Decorator)

动态地将附加职责附加到对象。装饰器为子类化提供了灵活的替代扩展功能。

class User {
  constructor(name, password) {
    this.name = name;
    this.password = password;
  }
}
class DecoratorUser {
  constructor(user, email, tel) {
    this.name = user.name;
    this.password = user.password;
    this.email = email;
    this.tel = tel;
  }
  get() {
    return this;
  }
}

export { User, DecoratorUser };

let user = new User("dao", "1234");
let decUser = new DecoratorUser(user, "julong1988@naver.com", "15526719999");
decUser.get();
