map operation functions in Clojure

Code

;; map_ops_2.clj

(merge-with + {:a 1 :b 2} {:b 3})

(update-vals {:a 1 :b 2} inc)

(defn greatest [x y] (if (< x y) y x))

(greatest 1 2)

(greatest 2 1)

(merge-with greatest {:a 1 :b 2} {:b 3})

(merge-with greatest {:a 1 :b 2} {:b 3})

Notes

• map operations - like adding, multiplying two maps and so on
