手写题: 寄生式组合继承

function Parent(name) {
    this.name = name;
    this.colors = ['red','blue','yellow']
}
Parent.prototype.getName = function () {
    console.log(this.name);
}
function Child(name) {
    Parent.call(this,name)
}
Child.prototype = Object.create(Parent.prototype)
Child.prototype.constructor = Child;
const child = new Child('wbt')
child.getName()
