Setup

var $ = window.$,
      lodash = window.lodash,
      underscore = window.underscore;
    
    var a = [],
      newArray = [],
      pi = Math.PI;
    
    for (var i = 1, max = 100; i <= max; i++) {
      a.push('Fundamental alert number ' + i);
    }

Test runner

Ready to run.

Testing in
TestOps/sec
jQuery.each
$.each(a, function(index, val) {
  newArray.push(val);
});

Good ol / classic for loop
for (var i = 0, len = a.length; i < len; i++) {
  newArray.push(
    a[i]
  );
}
ready
underscore.each
underscore.each(a, function(item) {
  newArray.push(
    item
  );
});
ready
Lo-Dash each
lodash.forEach(a, function(item) {
  newArray.push(
