Hello World Program in Clojure
(defn -main
(println "Hello World!"))Clojure is based on Lisp, and it uses more or less the same Lisp syntax.
(defn) defines the -main function
with one expression (println "Hello World!"),
which is a function call println
with a string argument "Hello World!".
In functional programming languages like Clojure, everything is an expression. There are no statements in Clojure.
If you run this program, you will get the following output, as expected:
Hello World!What's Next
If you are interested in learning Clojure programming, then you can set up a development environment before continuing.
