Title: Added pre-cached method for JS 'cache array lengths'

According to my new JSPerf, this method is MUCH faster than the other
two.
http://jsperf.com/browser-diet-cache-array-length/11/

var i = 0, len = arr.length;
for (i; i < len; i++) {
// Best - size is pre-calculated before the loop is initialized
}
