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.

I used JavaScript and was banging my head against the wall here trying to get around the timeout issue. I tried a ton of optimisations with no luck. Finally, I changed the Node.js runtime version from 8+ to 10+. Presto! Slightly empty vitory, but at this stage I'll take it.
