How do you return from a function early in Clojure?

Question

Common Lisp has return-from; is there any sort of return in Clojure for when you want to return early from a function?

Answer 1

As an alternative you could use cond . And if on some conditions you would need to evaluate multiple expressions use do. Here is an example:

(defn fact [x]
  (cond
    (< x 0) (do (println (str x " is negative number"))
                (throw (IllegalArgumentException. "x should be 0 or higher")))
    (<= x 1) 1
    :else (* x (fact (- x 1)))))
