Codewars

What is Codewars?

Achieve code mastery through challenge. Improve your skills by training with others on real code challenges. In our dojo, kata are real code challenges focused on improving skill and technique. Some train programming fundamentals, while others focus on complex problem solving. Each kata is crafted for and by the community. Each kata on the site is set to a Kyu/Dan rank, based on its subject area and difficulty. The community collectively determines rank in the Beta Process. You can advance through the ranks by completing kata at or above your rank - the harder the kata the faster you advance. Honor represents the level of respect a user has earned from the community, based on their skill and contributions. Honor is earned fastest through creating kata, crafting great solutions, and constructive comments
