Codewars is an educational community for computer programming. On the platform, software developers train on programming challenges known as kata. These discrete programming exercises train a range of skills in a variety of programming languages, and are completed within an online integrated development environment.
Ranks are used to indicate the proficiency of users and the difficulty of Kata. There are two classes of ranks, Kyu and Dan, which are divided in 8 levels each. By increasing order of proficiency/difficulty:
- 8 Kyu to 1 Kyu
- 1 Dan to 8 Dan
