Ready to run.

Testing in
TestOps/sec
jQuery.each
$.each(a, function(i, e) {
  e = pi;
});
ready
good old for loop
for (var i = 0, len = a.length; i < len; i++) {
  a[i] = pi;
};
ready
underscore.each
_.each(a, function(e) {
  e = pi;
});
ready
Less efficient for loop
for (var i = 0; i < a.length; i++) {
  a[i] = pi;
};
ready
