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.

Also every instance of an object will create a deep copy of the class functions it inherits which could lead to performance issues on large project. Using .prototype does not create a deep copy. But I do agree this style looks neater.
According to MDN, __proto__ is deprecated and should not be used. I would not recommend this solution. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/proto
