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.

Expensive, but very creative and clever. Great job!
absolutely laconic
outstanding!
Beautifully done, thanks!
Hard to beat, impressive work!
Amazing!
Great job! Super elegant.
Very clever use of short-circuit evaluation (&&). This makes sure that one never tries to access the array at the illegal argument (position) length(arr)+1. Great job.
Super elegant! Much better than my solution and superb use of the ternary operator.
