  • user=> (println "Hello world.")
    Hello world.
    user=> (def items [ "hello" :a 1 (list :b 2) \c {:d 4} #{5 6 7} ])
    ; println is for human-readable output, like a report. Note the lack of quotes around the string "hello" and the unescaped letter "c". 
    user=> (println items)
    [hello :a 1 (:b 2) c {:d 4} #{5 6 7}]
    ; prn outputs items in a machine-readable format, such as in a source
    ; file. Note the double-quotes around the string "hello" and the escaped letter "c".
    user=> (prn items)
    ["hello" :a 1 (:b 2) \c {:d 4} #{5 6 7}]
    ; pr-str produces a string with escaped punctuation, so that println yields the same result as the original prn call.
    user=> (println (pr-str items))
    ["hello" :a 1 (:b 2) \c {:d 4} #{5 6 7}]
    ; Calling println w/o args outputs a newline and nothing else.
    user=> (println)
    ; The newline function does the same.
    user=> (newline)
