It's not clear whether you're to return a value or output a value. In the Typescript scaffolding, no return type is notated.

I added it this morning when I first saw your message. Did that fix the problem for you? It's frustrating that the system didn't tell me there was a problem. You're the first person to mention it. Hopefully it's working for you now.

This hasn't come up before, and the code is validating fine. Is this happening to you every time you run your code?

Haha! Yup :) Sorry about that.

Sorry. This was my first kata, so I wasn't sure how to add random tests. I just added them now. Thanks!

Description still conflicts with the test cases. The strings contain more than just parentheses.
