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: “cond-> and cond->>.” We devote some time to two functions that are indispensable when computations require variation. Selected quotes: “Our love of Clojure is unconditional!” “These are all about conditional operations.” “It’s shorter and easier to understand, which is uncommon in develo ..read more
