If it's not said then it's ouside the specs.

Unless it's not mentioned in the kata but you actually need to handle it, it's not an issue.

Are you sure you are casting the result? (the kata is specific in wanting string return)

Very true! Thanks for the note.

I think it just showed you the preview, possibly showing the rest if you selected edit or the like, but not sure.

Anyway, glad you appreciated my work and let me know if I can be of further help (adding random tests to the JS version or improving my work or whatever else) :)

Of course it does, otherwise you would be notified that the tests are not completed.

And I don't remember correctly, but I think you can either re-run the tests yourself or see the past runs.

Btw, the code ends with a return statement, as expected :)
