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 I ask why did you choose "f" as your variable over "i"? is there a word associated with it?
^ one liner [562]
the same here. I had this problem once with another kata and turned out I was printing the value instead of returing it. this time I can't find any mistake but I gueess the problem is on our end again ;)

I'm getting the same output as it wants from me but it throws an error after testing. I double checked and changed the brackets, dashline and even added the quotation marks but it still says "None should equal '(123) 456-7890' "
*Update: ah I'm sorry. It's sattled, I noticed I was printing the resault and not retruning it 🤦🏻♂️🤦🏻♂️
