注释很详细，直接上代码
涉及知识点：
- 构造函数实现类
- ES6类的写法
- 原型链的应用

* 好眼熟，之前咱好像在题目规定使用class时用构造函数也写了一遍

function Human(name) {

function Chinese(name, age) {
Human.call(this, name);

}
//在Human的原型上定义getName方法
Human.prototype.getName = function () {
return this.name;
};
//继承Human原型(记得new而不是直接赋值，因为js赋值的是地址，会将两者绑定)
Chinese.prototype = Object.create(Human.prototype);
//重写Chinese的构造函数将原型链的constructor指回Chinese，正所谓作业可以抄但名字记得改
Chinese.prototype.constructor = Chinese;
//在Chinese的原型上定义getAge方法
Chinese.prototype.getAge = function () {
return this.age;
};
//这里我们再来用Es6的class语法来实现一遍，体验一下Es6的语法的便捷
class Human1 {
constructor(name) {
this.name = name;
