顯露的模塊模式

Question

我很好奇，如果任何人有以下兩種方式來公開顯露的模塊模式參數中的任何偏好：

圖表1：

DocReview.DocumentsApp = (
    ((DocReview, Backbone) -> 
     console.log("body") 
    )(window.DocReview, window.Backbone)) 

哪個編譯爲

DocReview.DocumentsApp = (function(DocReview, Backbone) { 
    return console.log("body"); 
    })(window.DocReview, window.Backbone); 

圖表2：

DocReview.DocumentsApp = do(DocReview = window.DocReview, Backbone = window.Backbone) -> 
    console.log("body") 

哪個編譯成

DocReview.DocumentsApp = (function(DocReview, Backbone) { 
    if (DocReview == null) DocReview = window.DocReview; 
    if (Backbone == null) Backbone = window.Backbone; 
    return console.log("body"); 
    })(DocReview, Backbone); 

我覺得我比較了做關鍵字的第二種方式，因爲它是整潔的CoffeeScript，但我不知道。

有人對此事分享意見嗎？

Answer 1

另一種選擇：

DocReview.DocumentsApp = do ({DocReview, Backbone} = window) -> 
    console.log "body" 

編譯爲：

DocReview.DocumentsApp = (function(_arg) { 
    var Backbone, DocReview, _ref; 
    _ref = _arg != null ? _arg : window, DocReview = _ref.DocReview, Backbone = _ref.Backbone; 
    return console.log("body"); 
})({ 
    DocReview: DocReview, 
    Backbone: Backbone 
});
