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.
You can replace
win === truewithwinbecause win is already a boolean
Or better yet, store the default language in an appropriately named variable so that whoever needs to maintain/update has an easier time.
