Question

In JavaScript, one would define a private member variable by making it a local variable in a function that returns a closure:

var count = (function(){
  var i = 0;
  return function (){ return i++; }
})();

This involves a define-function-then-call-it idiom that is fairly common in JavaScript, but I do not know how it translates in CoffeeScript. Any ideas?

Answer 1

You can use the do keyword

count = do ->
  i = 0
  -> i++
