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.
I'm not sure how to spoiler just the solution, but today I tried the same code as before, without changing it. It returned a syntax error this time. After "fixing" the error it accepted code which actually does contain a syntax error. Should be able to find my solution in the submissions now.
I'm getting the same problem. Pass 4900+ tests, then browser crashes. Can't submit solution after passing as "Attempt" never updates.
