Jun 4, 2012 at 16:29 comment added Phrogz Note that some interpreters (e.g. V8) will automatically cache the length of the array if the code is called enough times and it detects that the length is not modified by the loop. While caching the length is still nice, it may not provide a speed boost when your code is being invoked enough times to actually make a difference.
