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.

You've got the right idea, however you are returning a reversed array instead of a reversed integer.
Expected: 987654321, instead got: [9,8,7,6,5,4,3,2,1]. What's good about JavaScript is that if you use join("") it will automatically cast the integers to a string in which you can cast back to an integer.Loading more items...
