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 really struggled at first because of the lack of sample tests. I ended up just guessing based on comments that you could new Node() and passed that into loop_size in a test. Then console.logged it to see what I was actually dealing with. That gave me a look at the Node object. From there, the light bulbs started to go on, and I created this really ugly test. My first CW test! :-P
