Since you named the parameter scriptUrlsArr and your README example clearly expects the argument to be an array and your tests (well, test) uses an array as the only argument, you can probably remove the branch of the code that tests if the type of the argument is a string and handles that case. That case should cause an error, not succeed silently. It's not the correct usage of the API. Correct me if wrong.
