This person seems to think that "less code" is "faster code". Yes, I do have to give some credits to putting the number x number directly into the push call Are they really suggesting _results.push(number * number); is significantly faster than, say var result = number * number; _results.push(result); Because it's not. Though I do wonder why CoffeeScript doesn't do something like this to avoid the function call: _results[_i] = number * number;
