Is there a more lispy way to write this code?

Question

I've been learning Clojure, and since I come from a Ruby, and before that Java background, I have trouble thinking procedurally.

Is there a more 'lispy' way to write this code, or is this ok?

(defn foo
  ([s t]
     (let [x (+ 4 (- t s))]
       (if (> 2 (if (> 6 x)
                  x
                  6)
              x)
         x
         2))))

Answer 1

In clojure, like in any other language, it is usually best to use built-in functions whenever applicable. So since clojure has a min and a max function, so you can replace your ifs with:

(max 2 (min 6 x))

If those functions did not exist in clojure's standard library, I would have recommended defining them because putting the logic for min and max into their own function leads to much nicer code than having it all in the foo function.
