In this guide, we will discuss Clojure Environment Setup. There are a variety of ways to work with Clojure as a programming language. We will look at two ways to work with Clojure programming.
- Leiningen − Leiningen is an essential tool to create, build, and automate Clojure projects.
- Eclipse Plugin − There is a plugin called CounterClockwise, which is available for Eclipse for carrying out Clojure development in the Eclipse IDE.
