Codewars
Achieve mastery through coding practice and developer mentorship

Codewars is a coding practice platform where developers solve progressively ranked coding exercises called "kata" directly in the browser. It supports over 55 programming languages and offers a community-driven environment for learning, mentorship, and competition. Users earn ranks and honor as they complete challenges, and can also contribute by creating their own kata or reviewing others' code.
Users solve ranked coding exercises (kata) in the browser, receive instant test-driven feedback, and can view community solutions to learn new techniques and improve their skills.
