JavaScript - Are loops really faster in reverse…?
I don't know if this question is valid in other languages or not, but I'm asking this specifically for JavaScript.
I see in some articles and questions that the fastest loop in JavaScript is something like:
for(var i = array.length; i--; )
Also in Sublime Text 2, when you try to write a loop, it suggests:
for (var i = Things.length - 1; i >= 0; i--) {
Things[i]
};
I want to know, why is i-- faster than i++ in loops?
