Sample of the way to use each approach to comment code in Clojure

clojure-comments.clj

; This line is commented out
(this-code-will-be-executed) ; (this-code-will-not-be-executed)

(defn developing-function [& _] )
(comment ; Use this in development. Remove it when finish.
  (developing-fuction 1 2 3 4)) ; Send inner expression to the repl

; #_ is use to comment out an expression quickly
