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.
See the hint from "bkilrain":
"I guess they aren't passing because you are modifying the original objects passed in somehow. That wasn't specificied in the kata description but if you refactor to preserve the original objects, they will pass."
Random tests for JavaScript are broken, the tests expect "0" even if there are a lot of ingredients left.
