Summary: Advanced FP Techniques

In this brief chapter, we discussed how DSLs could improve our code, making it easier to use and maintain. Furthermore, for smaller applications, creating a DSL using functions is often good enough. But several more advanced FP techniques exist, including two we discussed here. Other techniques include tagless final and free monads, which might be useful in larger applications, though we should consider drawbacks such as added complexity and, potentially, poorer performance.
