Question

Can someone help me translate the following to coffeescript?

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

CoffeeScript equivalent will be the following.

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

You can use this site for this purpose http://js2coffee.org/ or you can download and install the code from https://github.com/rstacruz/js2coffee and use it on your machine.
