CodeWars

A platform for completing user-created exercises and challenges. Use it to sharpen your skills in a variety of different languages.

CodeWars is a community-driven code challenge platform for programmers. With support for more than 50+ programming languages, and a free subscription option, CodeWars can help you reach higher levels of understanding if you put in the effort.

Each challenge or “Kata” has a different level of difficulty, and completing challenges adds points to your profile. Upon working on your “Kata”, you are given an online IDE to work with, as well as unit testing and the ability to import native libraries straight from the IDE.

After completing each challenge, you are presented with the answer you submitted and how it compared to other submissions. You can choose between the best solutions, shortest solutions, or the most “clever” solutions.
