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.
Fewer lines of code isn't equal to good/best code though. Readability matters a great deal in large codebases with all sorts of developers coming in-and-out on projects.
