Ep 052: Functions! Functions! Functions!

Functional Design in Clojure

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

If you have a question 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, our topic is: "Functions! Functions! Functions!" We wonder how we could function without these critical building blocks, so we catagorize their varied uses.

Selected quotes:

• "Functions put the fun in functional."

• "Each function category has a different mindset."
• "Programming is more fun when you're only thinking about the problem in front of you."
• "Naming bits of computation helps you understand an abstraction without having to dip into it."
• "So you don't want the function to be called 'write-or-fetch-or-sleep-or-return!'?"
• "Side effecting functions shouldn't think. They are grunts."
• "The I/O fairy hands you data, and you get it all transformed with pure functions, and then you hand it back to the I/O fairy."
• "That Twitter use case, that has a lot more side effects."
