MOOCs and Video Courses

Video courses can help when you want a guided sequence and a predictable pace, but they age faster than books or reference docs. Tooling, ecosystem libraries, and course marketplaces change, so pick courses by teaching quality and freshness, not by brand alone.

Start from the official training directory

The safest starting point is the official Clojure training page. It is maintained as a living directory and currently points individual learners to courses such as:

• Lambda Island for Clojure and ClojureScript development
• PurelyFunctional.tv for broader functional-programming depth
• Learning Clojure on Udemy
• learnreitit.com, learnpedestal.com, and learndatomic.com for stack-specific backend work
• learnreframe.com and learnreagent.com for front-end ClojureScript tracks
• clojure.stream for a broader mix of courses, podcasts, and workshops

That directory is more reliable than memorizing a fixed list of course marketplaces inside this appendix.

What to look for before you buy or subscribe

A good course for a Java engineer should show:

• a current workflow based on the Clojure CLI, REPL, and modern editor tooling
• real code, not slide-heavy theory
• explicit treatment of collections, namespaces, testing, side effects, and interop
• concrete examples that look like services, handlers, data processing, or JVM application code

Be cautious with courses that:

• spend a long time on generic FP motivation but not much time on actual Clojure
• rely on obviously dated tooling without explaining that it is dated
• never show the REPL or a realistic project structure
• focus on toy puzzles only

A practical path by learner type

If you are a Java backend developer

Start with one general fundamentals course, then add one stack-specific course that matches your target work. For example, a general course plus Reitit, Pedestal, or Datomic is usually more useful than buying three “intro” courses that repeat the same syntax.

If you are aiming at ClojureScript

Choose a course that teaches ClojureScript through a real UI stack such as Re-frame or Reagent, not one that treats the browser as an afterthought.

Quick environment check before committing to a course

If a course assumes you can evaluate code locally, make sure your setup works first:

1clojure -e "(println (map inc [1 2 3]))"

If that is painful on day one, fix the environment before paying for more content. In Clojure, the learning loop depends heavily on being able to try small expressions immediately.

One current example worth knowing

Pluralsight’s Clojure Fundamentals is currently available and beginner-oriented. That makes it a reasonable option if you already use Pluralsight at work and want a structured baseline before moving into more specialized material.
