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.

Thanks everyone, your explanations helped me a lot.
Could someone please explain what's going on here?
Array(n+1).join(str)
I couldn't find anything on the net about Array() taking parameters. Is that an object or a method or what?
