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.

@tuxino: absolutely right. Good answer!
Oh, and the issue-marker is only supposed to be used, when there is something wrong with the kata.
The kata works fine for JavaScript - there's almost 300 people who managed to solve it, so the issue is with your solution, not the kata.
Factorials grow absurdly quickly. So much that normal integer variables can't contain them.
Luckily, in this case you don't actually need to calculate the factorial of any number. Try shuffling around the terms in the choose function.
