1. IIFE, 為了避免污染全域的環境，然後此 funciton 當他建構好後又會立即的執行。
2. 忽略了 javascript closure 的特性, 可以用 let 定義一個新變數，值為 i 。又或者是把 ajax call 那邊建立一個 funciton，把 i 傳入的方式，避免掉 closure。
3. CDN，減少自身流量，快速 (依使用者位置，對應局離近的伺服器。或有可能使用者有 cache 了）等好處大於放本機端。
4. 因為 bind 在 IE8 沒支援，我們可以利用 apply 模擬出類似的作法，簡單方式像以下，也可以用 polyfill 來處理 (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind)
```
function bind(fn, obj){
return function(){
fn.apply(obj, arguments);
}
}
