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