;; This is a demonstration of a question I have about Clojure
;; I want a function like `map-kv`, but I'm not aware of one that behaves this way
;; My hypothetical `map-kv` works like Underscore.js/Lodash.js `map` works

(defn classify-nums [hash-or-vector]
  (map-kv (fn [key-or-index value]
            (if (odd? value)
              "is odd"
              "is even"))))

(classify-nums {:a 1 :b 3 :c 4}) ; => {:a "is odd" :b "is odd" :c "is even}
(classify-nums [1 3 4]) ; => {0 "is odd" 1 "is odd" 2 "is even"}

;; I got the answer! Thanks to luma on Freenode #clojure -- `reduce-kv` https://clojuredocs.org/clojure.core/reduce-kv
