Ep 058: Reducing It Down

Functional Design in Clojure

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 [email protected], or join the #clojuredesign-podcast channel on the Clojurians Slack.

This week, the topic is: "Reduce and reducing functions" We take a long hard look at reduce and find the first of many generally useful nuggets inside.

Selected quotes:

• "Parentheses are a joy, they are hugs around your code."
• "You want to boil it down into a result, so you use reduce."
• "We've taken ahold of the cooking metaphors and are just running with it!"
• "Reducing functions are a backbone of functional programming, because we don't have mutation."
• "Understanding reduce is really important for understanding functional programming."
