acebone, Martin Honnen,

Here is an example

if (window.Array && Array.prototype && !Array.prototype.push)
  Array.prototype.push = _Array_push;
function _Array_push () {
  for (var a = 0; a < arguments.length; a++)
    this[this.length] = arguments[a];
  return this.length;
}
var a = ['Kibo', 'Maho', 'Xibo'];
a.push('Marco', 'Jaffo');
alert(a)
