for-loop - 如何将 JavaScript for 循环转换为 CoffeeScript？

Question

for (i = 0; i < 10; i++) {

    doStuff();

}

这是我想要转换为 CoffeeScript 的 JavaScript 代码。

Answer 1

doStuff() for i in [0 .. 9]

准确的翻译是:

doStuff() for i in [0...10]

您需要小心“..”与“...”，例如:

count = 0
doStuff() for i in [0..count] #still executes once!

所以你想，没问题...我将循环直到 count-1!

count = 0
doStuff() for i in [0..count-1] #executes twice!! '0' and then '-1'

字面翻译:

for (var i = 0; i < someCount; ++i)
  doStuff()

是

for i in [0...someCount]
  doStuff()
