ES6新增的语法糖-class

ES5中的面向对象

  //1.构造函数

    function Person(name, age) {

this.name = name;

        this.age = age;

    }

Person.prototype = {

constructor:Person,

        print(){

console.log("我叫" +this.name +',今年' +this.age +'岁');

        }

}

let person =new Person('张三',19);

    console.log(person);

    //2.ES6通过class面向对象

    class Person {

constructor(name,age){

this.name = name;

            this.age = age;

        }

print(){

console.log("我叫" +this.name +',今年' +this.age +'岁')

}

}

let person =new Person('张三',19);

    console.log(person);
