循環輸出[對象，對象，對象對象]

Question

最近我一直在學習一些在線課程，試圖理解編程的基礎知識，逐漸嘗試增加我學習的複雜性。然而，我似乎無法控制我的循環的輸出，我要麼獲得最後一個值或[對象，對象對象，對象對象，對象，對象]

任何幫助將不勝感激，我相信這很簡單，但我已經嘗試過爲了各自的目標，迄今爲止還沒有運氣。

我希望有人可以幫助控制循環的輸出。

Answer 1

您還沒有表現出任何的代碼，但是我可以猜到，你的問題是典型的東西在JavaScript：

JavaScript closure inside loops – simple practical example

退房neurosnap的答案。

http://coffeescript.org/#loops 在CoffeeScript的是更簡單：

for filename in list 
    do (filename) -> 
    fs.readFile filename, (err, contents) -> 
     compile filename, contents.toString() 

基本上，你需要裏面的一個lambda/IIFE for循環在JavaScript中循環，以避免您的問題。
