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.

Can somebody explain this code?
its a mistake. I suppose that it must be strings test. Because if we use numbers it will output 'Good 1 Joe' or 'Good Morning 1' or 'Good 1 1'. To my mind, conditions should be changed.
