This repository contains practical code examples in multiple languages for learning about recursion schemes.
Just dive into the directory named after your favorite language; /schemes contains the implementation of different recursion schemes while /examples/<example> applies them to some toy problem.
There is no guarantee of correctness, and I had to make some interpretations to port them to Python, C++, and JavaScript. Nonetheless, I hope the short and naive implementation, as well as the examples, can help you in your journey.
Awesome Recursion Schemes is an excellent curation of other resources.
