title: JavaScript equivalent of Python's rsplit
body: <blockquote>
  <p>str.rsplit([sep[, maxsplit]])</p>
  <p>Return a
  list of the words in the string, using
  sep as the delimiter string. If
  maxsplit is given, at most maxsplit
  splits are done, the rightmost ones.
  If sep is not specified or None, any
  whitespace string is a separator.
  Except for splitting from the right,
  rsplit() behaves like split() which is
  described in detail below.</p>
