Hola,
I'm looking for a function that updates a map value by calling a
function on it.
(def foo {:a 1})
So instead of this:
(assoc foo :a (inc (:a foo))) ; => {:a 2}
Something like this:
(map-fn foo :a inc) ; => {:a 2}
Does that exist somewhere, or should I be doing this in a different
way? If not, shouldn't it be included?
(defn map-fn
[m key fn & args]
(assoc m key (apply fn (get m key) args)))
Cheers,
Jeff
