(first [1 2 3])

;; In addition to first, you’ll often want to get the remaining elements in a collection. There are two ways to do this:
;; (rest [1 2 3])
;; (next [1 2 3])


;; rest and next both return “everything but the first element”. They differ only by what happens when there are no remaining elements:
;; (rest [1])
;; (next [1])

;; We can get the final element of any collection with last:
;; (last [1 2 3])
