Functional Programming: The Art of Folding the Problem Space
This article explores the differences between functional programming (using Haskell as an example) and imperative programming when solving complex problems. Imperative programming can easily lead to code bloat, like drawing a straight line on paper, while functional programming is like folding the paper, cleverly "folding" the problem space, reducing dimensionality, and ultimately achieving the goal with concise code. The article uses the author's practical experience to illustrate how functional programming builds small modules and combines them to create rich ecosystems, and how to use features like monads to achieve elegant code combinations, ultimately avoiding the common code bloat and maintainability issues of imperative programming.
