使用parents方法填充子类的数组

// 父类
class Parent {
  constructor(name) {
    this.name = name;
  }

  sayHello() {
    console.log(`Hello, my name is ${this.name}`);
  }
}

// 子类
class Child extends Parent {
  constructor(name, age) {
    super(name);
    this.age = age;
  }
}

// 使用parents方法填充子类的数组
Child.prototype.__proto__ = Parent.prototype;

// 创建子类的实例
const child = new Child('John', 20);

// 调用继承的父类方法
child.sayHello(); // 输出：Hello, my name is John

Child.prototype = Object.create(Parent.prototype);
Child.prototype.constructor = Child;
