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 think the disourse comments simply meant the 'else' block is unnecessary
yeah, sure. If statment is true then it is not end of the word, this way you dont need to do else, becouse if first statement is false, then you should add . at the end. Try it.
Could you elaborate on that? As far as I can see, the else statement is needed so that if no nextWord is given then it must be the end of the string and the function should put a period at the end.
in format() function u dont need else statment. And its clever.
