;; Create a new map associating:
;; - "John" to :first-name
;; - "Doe" to :last-name
{:first-name "John"
 :last-name "Doe"}
=> {:first-name "John", :last-name "Doe"}

;; Add the age of John Doe to the map:
;; Associate the value 31 to the key :age
(assoc
  {:first-name "John"
   :last-name "Doe"}
  :age 31)
=> {:first-name "John", :last-name "Doe", :age 31}

;; Retrieve the first name of John Doe
;; Search for the key :first-name
(get
 {:first-name "John"
  :last-name "Doe"}
  :first-name)
