Clojure was formed in October 2011. Since then, it has focused on Clojure and related Lisp languages, such as Common Lisp and Scheme, all of which have strongly influenced the design of Clojure and the approach Clojure takes in approaching software design.
Clojure also has Java as its foundational platform. Clojure’s focus is not on the Java language but on the JVM and associated libraries. The JVM provides massive amounts of power for Clojure b/c you can use any Java library from Clojure, and it is pretty easy and clean to do so. Existing Java libraries can be wrapped in a functional approach with Clojure, thus providing a more functional and data-oriented approach to using the libraries. It gives the libraries a Clojury and Lispy feel.
