Object--->Data

那么如何声明类-->并非数据

 

Object--declare

var obj1=new Object();

var obj2=new Boolean;

var date1=new date();

var obj3={};

var obj4={name:'roboce',age:21};

 

BOM,DOM,Js Object

Array,Boolean,Date,Math,Number,String,RegExp,Global,

 

javascript基本组成

Object,variable,function

 Object--save data(property,and method)

function--sava logic and function
