Functional programming achieves code reuse by abstracting out generic pieces of machinery, customizable via higher-order functions.
函数式编程通过提取通用的功能部分来实现代码重用，可通过高阶函数进行定制。

Functional languages achieve reuse at a coarser-grained level than object-oriented languages, extracting common machinery with parameterized behavior.
相比于面向对象语言，函数式语言在一个较粗粒度级别上实现重用，使用参数化行为提取常用的实现功能。
