what’s the returned result as below?
s = ‘abcd’;
return s.split(‘x’);
it’ll return a null array or an undefined object?
Thanks!

an array with a single string element.

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.
