It generates every possible 4-letter English word to ever exist, assuming no new letters are added to English. Why 4 letters? Because. Basically, it is just a list of every combination of 4 characters. But it was fun to code. I split it into 3 scrollable lists, to find words easier.
Included/Found words: Code, Cats, Dogs, Game, Play, List, Find, and all the other ones. Also any 4-letter names. I hid "*SECRET*" in the list somewhere. Can you find it (look inside and look around for answer)?
