用 Clojure 的方式解决问题（Rafal Dittwald）

Rafal Dittwald's Clojure/north talk shows how to move from writing Java-style code in Clojure to thinking in data-driven, functional terms. He walks through a JavaScript example, refactoring imperative code step by step into a functional core.

Why HN likes it: HN repeatedly recommends it as a fantastic demonstration of procedural, OOP and FP approaches to the same problem, and of functional core and imperative shell.

“I urge you to watch this fantastic video which illustrates procedural, OOP(lite), and FP approaches to a sample problem”
