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.

ok, thanks
Problem in JS. Basic tests- ok. But the attempt-test "expected undefined to equal '15:00:34'" fails. It is not clear what exactly is wrong.
I see that there was already a similar problem below. In the console, my code also works correctly with the value of the string '14:60:34', returning '15:00:34'
