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.

If one has a linked list with tens of thousands of records in Javascript, I think that's likely a problem bigger problem than this function blowing out the stack.
Though, I am disappointed to learn that most browsers haven't implemented tail recursion optimization, even though it was in the ES2015 spec nearly 10 years ago. It's such a boilerplate program optimization, I'd assumed it would have happened by now. Go Safari, I guess.
That's a cheating!)
That's clever, but it seems can't handle long orders -- stack overflow should happend due to recursion. That's why I won't vote 'Best Practices' but 'Clever'. Anyway, this is clean and pretty fine!
