From
https://clojuredocs.org/clojure.core/get
you’ll see that `get` accepts an additional argument, the default value, which
e.g. the keyword does not.
As for getting stuff out of maps, the idiomatic way is
(def m {:a 1 :b 2})
(:b m)
;; => 2
There is otherwise a nice discussion about the finer points of this here:
