Bottom Up vs Top Down Design in Clojure - Mark Bastian

中文导读
Mark Bastian 对比了自顶向下的面向对象设计（OOP）与 Clojure 中自底向上的数据驱动设计。他通过将一款棋盘游戏抽象为纯数据加一组微小可复用的函数，与需要 22 个类构建的 OOP 版本做了鲜明对照。
为什么 HN 推它
HN 社区反复推荐的经典演讲，许多程序员正是看完它才真正参透了数据导向与 REPL 驱动的自底向上设计精髓。
「正是这场演讲让我真正搞懂了该如何用这种范式去架构程序。」HN 网友原话：is the talk that really made it clear to me how to design programs this way.
英文原摘要（HackerTube / Claude 整理）
Mark Bastian contrasts top-down object-oriented design with bottom-up, data-oriented design in Clojure. He models a board game as plain data plus small composable functions and compares it with a roughly 22-class OOP version.
HN repeatedly recommends it as the talk that made data-oriented, REPL-driven bottom-up design click.
HN 上的提及
Here's a more realistic comparison between classic Java OOP design vs the more data-oriented approach to design encouraged in functional languages like Clojure
One of my favorite videos from Clojure Conj last year
I think, a "Data Driven Development" approach would make a lot of implementations easier.
It is however a very good tool to do bottom up design.
I highly recommend this talk from Mark Bastian in Clojure/conj 2015
