Arrays: concat vs append (v2)

Revision 2 of this benchmark created by denim2x on

Setup

this.array = [];
    for (var i = 1e3-1; i >= 0; --i) {
      this.array[i] = i;
    }
    
    Array.prototype.append = function (array) {
      Array.prototype.push.apply(this, array);
      return this;
    };
    Array.prototype.append2 = function (array) {
      var size = array.length;
      for (var i = 0; i < size; i++) this.push(array[i]);
      return this;
    };
