When I started learning clojure I found it very difficult to understand the language terminologies. It might not be the case with others. I will try to make sure that this tutorial should be for the beginners may be Students who wants to try out the Clojure.

Note:- I am noit Clojure expert so if you see a bug please correct me.

Clojure is a Functional Programming language written by Rich Hickey. Clojure is a List Dialect. Clojure is a hosted Language which means it runs on top of JVM (Java Virtual Machine).

• JVM processes execute Java bytecode.
• Usually, the Java Compiler produces Java bytecode from Java source code.
• JAR files are collections of Java bytecode.
• Java programs are usually distributed as JAR files.
• The Java program clojure.jar reads Clojure source code and produces Java bytecode.
• That Java bytecode is then executed by the same JVM process already running clojure.jar.

Defacto clojure dependency, build tool. We will see some of the lein commands which are very handy.

To create a new Clojure project

lein new app clojurebasics

To run a project and do a quick testing

lein run

To create a uberjar

lein uberjar

To run the created uber jar

java -jar target/uberjar/clojurebasics-0.1.0-SNAPSHOT-standalone.jar

To connect the REPL (READ, EVAL, PRINT, LOOP)

lein repl

There are many more lein commands to learn. Please check out the Lein Official website for it.
