I consider this book a companion on the journey to mastering the craft of coding. With it, you’ll always be able to achieve higher-quality…

What does refactoring have to do with domain modeling in functional programming?

It turns out that the very essence of code improvement is closely tied to enhancing its capability to handle the intricacies of a specific domain. This implies that even when refactoring a domain-agnostic mechanism in our code, our objective is to address previously inaccessible aspects of the domain.

Another important aspect of refactoring is that functional languages make it more desirable and safer, thanks to core principles such as purity and immutability.

Although there might not be an abundance of books on domain modeling in functional programming, I…
