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

Frameworks

Let’s define a framework as any library that contains one or more functions that accept callbacks.

Web frameworks are great for beginner developers who need to get stuff done. But they ultimately force you into a corner. In most applications, experienced developers need to retain control. Libraries are better.
