(def class1 {:people '({:name "John" :age "25"} {:name "Harry" :age
"23"} {:name "Peter" :age "24"})}) or (def class1 {:people [{:name
"John" :age "25"} {:name "Harry" :age "23"} {:name "Peter" :age
"24"}]}) is probably what you want.
(mapv (juxt :name :age) (:people class1)) on either of those will give
you your result.
