测试JS基本类型以及对象的引用

自己敲的。
  1 <script src="https://ajax.googleapis.com/ajax/libs/prototype/1.7.1.0/prototype.js" type="text/javascript"></script>

 <script type="text/javascript" language="javascript" charset="utf-8">
 var a = new Number(5);
 var b = a;
 a = 6;
 console.info(b);//输出一个number对象
 console.info(b.toString());//值为5
 var c = 5;
 console.info(c);//直接打印5,那么这个是基本数据类型。
 console.info(a == b);//false
 console.info(a === b);//false
 a = 5;
 console.info(a == b);//true,值相等,但确切说，不是同一个对象
 console.info(a === b);//false
 a = 5;
 b = a;
 console.info(a == b);//true  现在是同一对象了
 console.info(a === b);//true 

 function Man(){
     this.love = "爱";
 }
 Man.prototype = {
     __proto__:new Man(),//不加这句的话，就不会有名字。Man对象的原型名就叫Man，但意思又是继承了Man,把Man中的属性弄成了，反正不要这样。
     "name":"小王",
     "age":23,
     sex:"男"
 }
 var m = new Man();//打印的对象
 //m.prototype.name = "小李";//m，实例无法更改原型属性
 Man.prototype.name = "小李";
 var m2 = m;
 m2.love="不爱";
 console.info(m);
 console.info(m.love);//不爱，指向同一个对象。
 console.info(m == m2);//true
 console.info(m === m2);//true

擦，地址忘了。叉了就忘了。
