    Question Help please! Javascript question

    what's the returned result as below?

    s = 'abcd';
    return s.split('x');

    it'll return a null array or an undefined object?

    Thanks!

    For future reference, you'll find that Mozilla's Javascript reference is a good resource.

    The page about the split method says:

    When the string is empty, split returns an array containing one empty string, rather than an empty array.
