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.
This kind of code returns only one row, not all of them. Output function exists, but isn't ever called (?). Also, the result should be returned, not printed to console.
Make sure you check exactly where your add the \n marker, you dont add it on every iteration. Also, using case here is quite inefficient, check out loops.
