Empowering the next generation of Crystal developers, with a solid learning platform.
Exercism is a free, not-for-profit, open-source platform that aims to make programming accessible to everyone. It features code practicing, mentoring, test-driven development, an online editor, and much more.
Exercism has 67 (as of writing), including Crystal. The Crystal track on Exercism, features a learning mode that allows students to take on concepts and their set exercise, to be able to be able to practice while learning. The track also features above 90 practice exercises which let you practice Crystal by solving a wide range of puzzles/exercises.
You can choose to work either in our online editor, which doesn't require any downloads, only a web browser and an online connection. Or alternatively, you can work offline using Exercism CLI.
The track also features track-specific tooling, like a representer and an analyzer (planned launch in late August/September), these tools allow for automated feedback to a student. Thereby they can instantly get feedback on their solution.
