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.

One question. On the line where you wrote (reversedWord = str[i] + reversedWord;), I understand that when you do reversedWord = str[i], it will assign the individual letters of the str into reversedWord. But why is it that when you + reversedWord to str[i], it reverses the character?
