I was trying maps in REPL and found some interesting behavior.

user> {:name "prathamesh" :lang "clojure"}
{:name "prathamesh", :lang "clojure"}

user> {:name "prathamesh" :lang "clojure" :age 22}
{:age 22, :name "prathamesh", :lang "clojure"}

Why the order of elements changed in second example?

hash-maps don't have any guaranteed ordering. If you want ordering you need to use a sorted-map. ~BG
