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'm not sure where you want to re.iter over? It still requires a string, so you end up with having to join the input array so you have something to iter on.
(That would still require a string to be built)
