Question

I want to accomplish this in coffeescript:

for (i = 0, i < count, i++) {
 doSomething();
} // count is a number

But it is always handled as an array.

Is there way to prevent this? I have tried a while loop, but it didn´t work out for me.
Thanks!

First of all, you want to implement this:

for(i = 0; i < count; i++) { ... }

in CoffeeScript, not for(i = 0, ...).

There’s an example of this sort of thing right in the documentation:

countdown = (num for num in [10..1])

and the JavaScript version:

var countdown, num;

countdown = (function() {
  var _i, _results;
  _results = [];
  for (num = _i = 10; _i >= 1; num = --_i) {
    _results.push(num);
  }
  return _results;
})();

So you just want to use this:

for i in [1..count]
  doSomething()

or

doSomething() for i in [1..count]

Note the the range starts at 1 so that [1..count] gives you count iterations.
