Mapping a function on the values of a map in Clojure

Question

I want to transform one map of values to another map with the same keys but with a function applied to the values. I would think there was a function for doing this in the c

Answer 1

Here's a fairly idiomatic way to do this:

(defn map-function-on-map-vals [m f]
        (apply merge
               (map (fn [[k v]] {k (f v)})
                    m)))

Example:

user> (map-function-on-map-vals {1 1, 2 2, 3 3} inc))
{3 4, 2 3, 1 2}
