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.

It might be considered bad, because linear lookup is slow when compared to other alternatives. It can be replaced either with binary search which could be a couple of times faster, or, even better, constant time subtraction.
That would be theory, actual performance difference would have to be measured and verified.
Could you, please, explain, why it is a bad solution to use "the indexOf on the alphabetical-order literal"?
I'm new in programming, and it is an obvious solution for me as I don't know and don't understand many of the JS methods.
Thank you.
