The path to declarative programming
summary
Shows how to migrate an imperative codebase toward declarative (functional) programming by refactoring a real application step by step. Covers concrete techniques to make business logic more declarative and resilient to side effects, discusses trade-offs (simpler logical reasoning vs. harder implementation), and explains practical use of concepts like monad transformers without heavy math.
