An opinionated list of excellent Clojure learning materials

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

Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502
# Single-line version:
