模块化开发   闭包防止污染全局变量
    var name = "123";
    var init = (function (){ 
    		var name = "ABC";
    		function callName (){
    			console.log(name);
    		}
    		return function (){
    			callName();
    		} //接口
    }())
    init();





入口函数init
    var initLee = (function (){
    		var name = "456";
    		function callName(){
    			console.log(name);
    		}
    		return function(){
    			callName();
    		}
    }())
    intLee();
