需要對jQuery插件樣板文件進行哪些修改才能在打字稿中編譯？

Question

在jQuery plugin boilerplate有一些很棒的jQuery插件開發的啓動代碼，但是將代碼複製並粘貼到打印機中並編譯會導致編譯失敗。

錯誤來自undefined參數，它沒有被調用（故意使用），所以問題是需要進行哪些修改才能編譯它。它可以被刪除嗎？

Answer 1

製作undefined可選：

// the semi-colon before function invocation is a safety net against concatenated 
// scripts and/or other plugins which may not be closed properly. 
; (function ($ : any, window, document, undefined?) { 

// undefined is used here as the undefined global variable in ECMAScript 3 is 
// mutable (ie. it can be changed by someone else). undefined isn't really being 
// passed in so we can ensure the value of it is truly undefined. In ES5, undefined 
// can no longer be modified. 

這將使該模板編制，因爲不確定是不是傳遞給函數。
