Refactoring Clojure: Crafting an Elegant Markov Text Generator

This article details refactoring Clojure code that generates a first-order word-level Markov text. Instead of directly modifying the original, the author starts by characterizing its behavior with comprehensive tests. The refactored code uses clearer functions and a more understandable structure, employing `reduce` and recursive function calls for efficient text generation. The result is significantly improved readability and maintainability while preserving the original functionality.
