Ep 060: Reduce Done Quick

Each week, we discuss a different topic about Clojure and functional programming.

If you have a question or topic you'd like us to discuss, tweet @clojuredesign, send an email to feedback@clojuredesign.club, or join the #clojuredesign-podcast channel on the Clojurians Slack.

This week, the topic is: "Reducers." We look at clojure.core.reducers and how it extracts performance by composing reducing functions.

Selected quotes:

• "The seq abstraction, it's rather lazy."
• "It's amazing how much work laziness requires."
• "It doesn't work out as well. That's a wonderful way of saying 'wrong'."
• "Because ease of use was a design goal, they're pretty easy to use."
