super关键字用法
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; } }
