// 请补全JavaScript代码,完成类的继承。要求如下:
// 1. "Chinese"类继承于"Human"类
// 2. "Human"类实现一个函数"getName",返回该实例的"name"属性
// 3. "Chinese"类构造函数有两个参数,分别为"name"、"age"
// 4. "Chinese"类实现一个函数"getAge",返回该实例的"age"属性
class Human {
constructor(name) {
this.name = name
this.kingdom = 'animal'
this.color = ['yellow', 'white', 'brown', 'black']
}
// 补全代码
getName() {
return this.name;
}
}
// 补全代码
class Chinese extends Human {
constructor(name, age) {
super(name)
this.age = age
}
getAge() {
return this.age
}
}
let h = new Human("man")
console.log(h.getName())
let c = new Chinese("lihua", 18)
console.log(c.getName())
console.log(c.getAge())
