.. py:function:: ak.str.join(array, separator, *, highlevel=True, behavior=None, attrs=None)


    :param array: Array-like data (anything :py:obj:`ak.to_layout` recognizes).
    :param separator: separator to
                  insert between strings. If array-like, ``separator`` is broadcast
                  against ``array``.
    :type separator: str, bytes, or array of them to broadcast
    :param highlevel: If True, return an :py:obj:`ak.Array`; otherwise, return
                  a low-level :py:obj:`ak.contents.Content` subclass.
    :type highlevel: bool
    :param behavior: Custom :py:obj:`ak.behavior` for the output array, if
                 high-level.
    :type behavior: None or dict
    :param attrs: Custom attributes for the output array, if
              high-level.
    :type attrs: None or dict

Concatenate the strings in ``array``. The ``separator`` is inserted between
each string. If array-like, ``separator`` is broadcast against ``array`` which
permits a unique separator for each list of strings in ``array``.

Note: this function does not raise an error if the ``array`` does not
contain any string or bytestring data.

Requires the pyarrow library and calls
`pyarrow.compute.binary_join <https://arrow.apache.org/docs/python/generated/pyarrow.compute.binary_join.html>`__.
