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 don't think you should use \b in regular expression to get the words as it will fail for any words that contain non-latin characters. According to the definition of \b "https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions" Note: JavaScript's regular expression engine defines a specific set of characters to be "word" characters. Any character not in that set is considered a word break. This set of characters is fairly limited: it consists solely of the Roman alphabet in both upper- and lower-case, decimal digits, and the underscore character. Accented characters, such as "é" or "ü" are, unfortunately, treated as word breaks.
