Getting started with Clojure programming language, using the Clojure CLI and community tools.

A practical guide to learning Clojure, with step by step explanations of code and design decisions.

Clojure REPL Driven Developmentλ︎

Clojure repl driven development using Clojure aware editor

Clojure runs in a REPL process that provides instant feedback as code is written, encouraging experimentation and allowing effective designs to evolve rapidly and with confidence that comes with a clear understanding.

The REPL is the Clojure interactive environment used to create an run Clojure code, in both development and production. Quickly grow confidence with Clojure by evaluating, breaking, fixing and extending code in the REPL. All the while getting instant feedback on what the code is doing.

Adrian Cockcroft - formally Cloud Architect, Netflix

The most productive programmers I know are writing everything in Clojure and swearing by it and then just producing ridiculously sophisticated things in a very short time. And that programmer productivity matters.

About the bookλ︎

Practicalli Clojure provides a hands on approach to learning Clojure through the entire development workflow.

As we work through code we will discuss the concepts behind Clojure, including functional programming, "pure" functions and a stateless approach with persistent data structures, changing state safely, Java interoperability and tooling around Clojure.
