Ask HN: Are there any other topics in FP then simple composition and CT
Most of the articles about functional Programming are either simple descriptions on composition and currying or about how a monad is just a monoid in the category of endofunctors. I wonder if there are no other topics in this field. The articles on https://fsharpforfunandprofit.com/ are pretty good, particularly the ones about "Railway-Oriented Programming" (https://fsharpforfunandprofit.com/posts/recipe-part2/)
