说明

这是2014年由Strange Loop Conference发布的一部演讲，主题归在Functional programming。它讲的是transducers这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Rich Hickey introduces transducers in Clojure, a way to make map, filter and similar algorithms composable independent of the data source. This avoids duplicated implementations and intermediate collections across sequences, channels and streams.这些读者给出的理由，核心是：HN treats it as the original and definitive explanation of transducers, recommended whenever the concept comes up.讲法不绑某一条新闻，过几年仍然可以当材料看。从2014年到2025年，有6位不同的读者在6个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把transducers变成能跟着复述的例子。
