Question

谁能帮助我把以下内容翻译成咖啡字?

Step(
  function readSelf() {
    fs.readFile(__filename, this);
  },
  function capitalize(err, text) {
    if (err) throw err;
    return text.toUpperCase();
  },
  function showIt(err, newText) {
    if (err) throw err;
    console.log(newText);
  }
);

Answer 1

咖啡豆类对应物如下。

Step (readSelf = ->
  fs.readFile __filename, @
), (capitalize = (err, text) ->
  throw err  if err?
  text.toUpperCase()
), showIt = (err, newText) ->
  throw err  if err?
  console.log newText

Answer 2

Step(
  readSelf = -> fs.readFile __filename, @
  capitalize = (err, text) ->
    throw err if err
    text.toUpperCase()
  showIt = (err, newText) ->
    throw err if err
    console.log newText
)

Don t use converters ever. Your code can be corrupted after conversion. For example code, which you can see in previous post is incorrect. Because expression

throw err if err?

产生:

if (typeof err !== "undefined" && err !== null) {
  throw err;
}

I think it s not that you expect to see. I use site of coffee creator for my experiments with coffee. Don t use js2coffee site, there are some mistakes in conversion which can be critical. I had ones.. Good Luck!
