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.
