js怎么实现多继承

function Parent1() {
    this.name1 = 'Parent1';
}

Parent1.prototype.sayName1 = function () {
    console.log(this.name1);
};

function Parent2() {
    this.name2 = 'Parent2';
}

Parent2.prototype.sayName2 = function () {
    console.log(this.name2);
};

function Child() {
    Parent1.call(this);
    Parent2.call(this);
}

Child.prototype = Object.create(Parent1.prototype);
Object.setPrototypeOf(Child.prototype, Parent2.prototype);

const child = new Child();
child.sayName1(); 
child.sayName2();
