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.

Thanks!
Thanks for the hint. It was so slow. Optimized and passed the tests. Fun one, thanks for the tips.
Love this one. Thanks!!

Hint: to calculate the sum of all proper divisors of a number n, you don't need to test every number up until n / 2.
Ah probably, if the error you receive is a timeout after 12 seconds, then that means you have to optimize your code. Hint: to calculate the sum of all proper divisors of a number n, you don't need to test every number up until n / 2.
I've got the right solution for this in Javascript but I am getting "Execution Timed Out (12000 ms)". I refactored the code several times and still not working. The sample tests run fine but when I attempt it's always failing. Is it really possible? Could it be that the tests in that translation are provoking some issues?
