How to remove multiple keys from a map?

Question

I have a function that removes a key from a map:

(defn remove-key [key map]
  (into {}
        (remove (fn [[k v]] (#{key} k))
                map)))

(remov         


        

Answer 1

dissoc removes one or more keys from a map:

(dissoc {:foo 1 :bar 2 :baz 3} :foo :bar)

or, if you have the keys in a collection

(apply dissoc {:foo 1 :bar 2 :baz 3} [:foo :bar])
