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 believe that this is the best practice. By using "FindAll", you don't need to convert from IEnumerable to Array again, since FindAll already returns an array/list (this method is also available for lists).
Clever! from now I will use that Array Method. Good Job!
