Haskell: Surprisingly Procedural?
This article challenges the common misconceptions surrounding Haskell, arguing that it excels as a procedural language. It delves into Haskell's treatment of side effects as first-class values, explaining the underlying mechanics of `do` blocks and demonstrating the use of functions like `pure`, `fmap`, and `liftA2` to manipulate them. The author showcases `sequenceA` and `traverse` for handling collections of side effects and illustrates how these features enable efficient metaprogramming. A complex example demonstrates Haskell's strengths in managing state and caching, contrasting it with other languages' limitations. The article also explores advanced concepts like the `State` monad for improved control and streaming results.
