自定义对象

自定义对象：标准写法和白话写法
标准写法：new 实例化

var stu=new Object();
    stu.name="毛豆";
    stu.sex="男";
    stu.age=18;
    stu.job="tea";
    stu.eat=function (){
        //this 指代当前的对象
        return this.name+"啥都吃！";
    }
     //取值
    console.log(stu.name);
    console.log(stu.eat());
    //通过键直接取值
    console.log(stu["name"]);

白话写法

//抽象代码  封装对象
var students={
        name:"毛豆",
        sex:"男",
        eat:function (){
            return this.name+"啥都吃！";
        }
    };
    students['sleep']=function (){
        return this.name+"每天都睡！";
    }
    console.log(students.name);
    console.log(students['sex']);
    console.log(students);
    console.log(students.sleep());
