#5 - Add more endpoints
Right now there are basically two endpoint:
/words/beginner/random/:n
-- n random Beginner words. Problem is that external Word API provides multiple not ordered by usage definitions for one word, so have to choose randomly. Can be seen as feature though, user can learn new definition by mistake.
/words/
-- 10 Academic Intermediate words. Definition are good, fetched from vocabulary.com . Endpoints like this should be added by hand for other tags and difficulties.
