Revision 93 of this benchmark created by Dennis on

Setup

// Populate the base array
      var arr = [];
      for (var i = 0; i < 1000; i++) {
        arr[i] = i;
      }
    
      function someFn(i) {
        return i * 3 * 8;
      }
    
      var forEachFn = function(arrayLike, fn) {
        var i = 0,
          len = arrayLike.length;
        for (; i < len; i++) {
          fn(arrayLike[i]);
        }
      };
