Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

I designed this kata so that the code warrior would learn two things:
I threw an NaN test case into the mix to ensure that the second criterea is met. I knew that NaN would trip some people up, which was the point of including it.
If someone learns something new about NaN or the Number object then I think that's a good thing, even if it might seem counterintuitive.
I do agree that in a real world application you'd probably expect NaN to be rejected, but that wasn't my goal for this kata.
