# 進階-module pattern

**module相關-1:Mastering the Module** Pattern<https://toddmotto.com/mastering-the-module-pattern/>

module pattern經常會與 closure+self invoke function一起使用,

```javascript
var Module =
(function () {

 var x = "Hello!!"; // I will invoke myself

 return {
   name:"apple",
   test: function(){},
 }
})();
```

套用closure在module pattern上時, 過程都會返回一個使用`{}`Object Literal Notation的object.

**整理:** 1. 基本上只使用Object Literal Notation `var obj={}`就可以達到module化，包含member function, member property. 2. 若一般module想要使用/模擬private data/function, 則需要透過closure來達到.

**closure與module** 透過closure來達到private data/function, 除了運用在常見的module pattern+self invoke function上面, 也可以發生在`自訂object`內部. 可參考 1. <http://stackoverflow.com/questions/1535631/static-variables-in-javascript>以及 2. 下面ES6章節的[link2](http://stackoverflow.com/questions/27849064/how-to-implement-private-method-in-es6-class-with-traceur)都有提到.
