The Ultimate Guide to Learning Clojure for Free

Summary: There are many great resources out there for learning Clojure. Some resources are paid, but fortunately, many of the best resources are absolutely free.

Are you interested in learning Clojure? Would you like to start without risking your money on a book? Is there something that can help you even know whether you want to learn Clojure?

Well, yes.

I learned Clojure for free. I'm a bit of a cheapskate. For many years, I avoided spending money if there was a free alternative. I also keep an eye on resources that pop up around the internet.

I have assembled what I believe to be the best resources to start with if you want to get into Clojure but wish to spend $0.
