Codewars (and other code golfs) are a great way to become more familiar with a language when you're already handy with programming. In this video, I showcase Codewars, my favorite code golf site. To demonstrate how it works, I solve the "Tic-Tac-Toe Checker" Kata. (This is also just a great way to solve Tic-Tac-Toe in general. Also Rust!)
