technomancy

The Clojure Style Guide is pretty good overall. It's very detailed and most of its advice is solid. There are handful of places it makes bad recommendations or is missing some advice.

Many of these criticisms apply to the output of linters like clj-kondo as well.

An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

• 🔴 Mandatory (for both beginners and intermediates)
• 🟩 For beginners
• 🟨 For intermediates
