A beginner with Haskell is bound to be exposed, usually too early, to some fancy code illustrating either a cool feature of the language, or of its …

In Real World Haskell, Chapter 4. on Functional Programming:

Write foldl with foldr:

-- file: ch04/Fold.hs
myFoldl :: (a -> b -> a) -> a -> [b] -> a

myFoldl f z xs = foldr step id...

A catamorphism is a general abstraction that enables you to handle multiple values, for example in order to reduce them to a single value.

I am working through "Real World Haskell", which led to to a free PDF called "A tutorial on the universality and expressiveness of fold". It makes the point that a "fold" is "universal". I am wrest...

I'm looking for some really simple, easy-to-grasp explanations of recursion schemes and corecursion schemes (catamorphisms, anamorphisms, hylomorphisms etc.) which do not require following lots of ...

I am trying to get the product of a tree by using the fold function so far this is what I have. I am confused on how to use the fold method while transversing the tree

datatype 'a bin_tree = Leaf...

Members of the Elixir community often receive the question: “why should we use Elixir?” The answer to this nuanced question remains elusive, and this talk argues that the answer is not primarily technical. This talk argues that answering this question, as…

Programming is math and math is programming. But the kind of math that's useful in programming is not what they teach you in school. In fact it's much more interesting. Category theory seems to be esoteric…

Functional programming is increasing in popularity these days given the inherent problems with shared mutable state that is rife in the imperative world. As we march on to a world of multi and many-core chipsets, software…
