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.
Tests are wrong for TS/JS, 456 must return 15, not 5, as set when you start the kata. I suspect that the Attempt tests answer are wrong too. But I can't not check it because the console used to show info doesn't show me which numbers is testing in the Attempt.
