clojure Clojure destructuring Destructuring a map with default values
Example
Sometimes you want to destructure key under a map which might not be present in the map, but you want a default value for the destructured value. You can do that this way:
(def my-map {:a 3 :b 4})
(let [{a :a
b :b
:keys [c d]
:or {a 1
c 2}} my-map]
(println a b c d))
;= 3 4 2 nil
