How it works
The platform uses a martial-arts ranking system, from 8 kyu for beginners up to 1 kyu and dan ranks for experts, which makes practice feel like a game. It includes a discussion section for each kata, plus a way to create your own challenges for the community. Codewars is used by developers to keep their skills sharp and to prepare for interviews.
Codewars is completely free to use. It is best for developers who already know the basics of a language and want regular, fun practice, rather than a structured course with lessons and a teacher.
