Parameter description
Separator is required. String or regular expression, which separates stringObject from the specified place.
Optional. This parameter specifies the maximum length of the returned array. If this parameter is set, no more substrings are returned than the array specified by this parameter. If this parameter is not set, the entire string is split, regardless of its length.

However, if separator is a regular expression that contains a subexpression, the returned array contains the strings that match the subexpression (but does not include the text that matches the entire regular expression ).
