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.

Thank's! I saw it after submitting( It was my first Object Kata, so I tried all stuff to make it. And was very happy when all the test passed!)
Your loop here has no effect. You're not even using the value of key. If you remove the loop this will still work because you are returning the value of Languages[language] when language is a key in your object and defaulting to english in all other cases.
