Ep 075: Merge With Fun

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 [e-mail], or join the #clojuredesign-podcast channel on the Clojurians Slack.

This week, the topic is: "merge-with." We focus in on merge-with, a powerful function for aggregating data.

Selected quotes:

• "We pick up idioms from other people."
• "What sounds insane at face value actually starts to make a lot of sense."
• "It's just a filter, you don't even have to write a function for that."
• "The important part in the middle, where we might mess up, is all pure."
• "We don't just have an O(n) problem, we have an 0(n) API calls problem."
