We focus in on merge-with, a powerful function for aggregating data.

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: "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."
