;; let expression is an IIFE (provides lexical scope)

(let [name "Vick"
      msg  "Much appreciated"]
     (println (str "Thanks, " name))
     (println msg))
     ;; => Thanks, Vick
     ;; => Much appreciated!


;; anonymous function definition can be treated as an IIFE

((fn [name msg]
     (println (str "Thanks, " name))
     (println msg)) "Vick" "Much appreciated!")
     ;; => Thanks, Vick
     ;; => Much appreciated!


;; shorter syntax for an anonymous IIFE

(#((println (str "Thanks, " %1))
   (println %2)) "Vick" "Much appreciated!")
   ;; => Thanks, Vick
   ;; => Much appreciated!


;; named function expression, to be invoked later

(defn thx [name msg]
          (println (str "Thanks, " name))
          (println msg))
(thx "Vick" "Much appreciated!")
;; => Thanks, Vick
;; => Much appreciated!

Do you have the generated js?

I am surprised the initial version worked at all (misplaced parens) :)
