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.

Fixed
I think the ES2015 support via "babel" has broken this test (functions get reformatted by babel).
I know that it could be irittating, because similiar solutions passed (in the past) all tests, but in the description there is no information how functions should be transformed. In other words - you can't blame the kata if bad solution does not pass tests.
Facing the same problem :(
Failing due a very strict formatting on displaying function...
