Clojure - Predicates some

Returns the first logical true value for any predicate value of x in the collection of values.

Syntax

Following is the syntax.

(some p1 col)

Parameters − p1 is the predicate which needs to be tested. col is the collection of values which needs to be tested.

Return Value − Returns true if the predicate is true for every value, else false.

Example

Following is an example of some in Clojure.

(ns clojure.examples.example
   (:gen-class))
(defn Example []
   (println (some even? '(1 2 3 4))))
