闭包（2）

代码模式：闭包最强大的用途模块

<script>    function CoolModular(){        var something = "something";        var another = [1,2,3];        function doSomething()        {            console.log(something);        }        function doAnother()        {            console.log(another.join("!"));        }        return {            doSomething:doSomething,            doAnother:doAnother        }    }    var cool = CoolModular();    cool.doSomething();//something    cool.doAnother();//1!2!3!</script>
