Learning haskell has its challenges. Most notably the terseness of the function composition, giving IMO a longer learning curve to master the syntax. This terseness is due to its roots in mathematics and academia, and so the functions read unsurprisingly like algebraic formulas. I’ve been working my way through Project Euler to learn haskell in […]

Learning haskell recently has really highlighted the power of the built in classes of haskell. Compare a function in haskell to captialize the first letter in a sentence, vs c#. Haskell 1 2 3 4 5 import Data.Char   sentenceCase :: [Char] -> [Char] sentenceCase [] = [] sentenceCase (x:xs) = [toUpper x] ++ map […]
