About This Project

A few years ago, I had to learn fp-ts for work and got completely stuck. Pure functional programming was brand new to me, and most resources either jumped straight into heavy theory or didn’t give me a good way to actually practice. I kept wishing for a space where I could just experiment and learn by doing. This project is basically the tool I wish I’d had back then, with interactive exercises and small experiments so you can build intuition step by step.

I know AI can generate a lot of this code just fine now, and in that sense there’s arguably less “need” to learn these concepts than before. But I got into programming because I genuinely enjoy it, and learning new ways to think about code is part of the fun. Functional programming stretches your brain in a good way, and I think there’s value in understanding what’s going on under the hood.

I’m still learning this stuff myself, and the site grows as I do. If it helps make your fp-ts journey a little less confusing (and a bit more fun) than mine was, then it’s doing exactly what it’s meant to do.

If you have feedback, questions, or just want to say hi, you can reach me at mariefay.tech@gmail.com — I’d genuinely love to hear from you.
