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.

What about it? The answer is undefined, and JS will give some answer ( either

Don't change the order.

Expected: [4, 6, 3], instead got: [3, 4, 6]
Expected: [4, 5, 2, 1], instead got: [1, 4, 5, 2]
Expected: [2, 1, 3], instead got: [1, 2, 3]
smart solution!
Thanks for this Kata series!
