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.

i like how clean this looks
what is the + in +word.match(reg) doing here ? match should return an array with many items ? does it convert the first element to a number ?
I like it, but why not define the regex within the function that uses it?
why did you put in "comparator" and "reg"?
