使用JavaScript编写代码Dog类含有age属性和eat方法Animal类含有name属性和shount方法让Dog类继承Animal类

// Animal 类 class Animal { constructor(name) { this.name = name; }

shout() { console.log(${this.name} is shouting.); } }

// Dog 类继承 Animal 类 class Dog extends Animal { constructor(name, age) { super(name); this.age = age; }

eat() { console.log(The dog is eating.); } }

// 测试代码 const dog = new Dog('Max', 3); console.log(dog.name); // Max console.log(dog.age); // 3 dog.shout(); // Max is shouting dog.eat(); // The dog is eating.
