  24     ECMA Section: 15.4.4.3-1 Array.prototype.join()
  25     Description:  The elements of this object are converted to strings and
  26                   these strings are then concatenated, separated by comma
  27                   characters. The result is the same as if the built-in join
  28                   method were invoiked for this object with no argument.
