//类的定义
classAnimal {
//ES6中新型构造器
constructor(name) {
this.name= name;
}
//实例方法
sayName() {
console.log('My name is '+this.name);
}
}
//类的继承
classProgrammerextendsAnimal {
constructor(name) {
//直接调用父类构造器进行初始化
super(name);
}
program() {
console.log("I'm coding...");
}
}
//测试我们的类
varanimal=newAnimal('dummy'),
wayou=newProgrammer('wayou');
animal.sayName();//输出‘My name is dummy’
wayou.sayName();//输出‘My name is wayou’
wayou.program();//输出‘I'm coding...’
