In this guide, we will discuss Clojure Doseq Statement. The ‘doseq’ statement is similar to the ‘for each’ statement which is found in many other programming languages. The doseq statement is basically used to iterate over a sequence.

Syntax

Following is the general syntax of the doseq statement.

(doseq (sequence)
   statement#1)

Following is the diagrammatic representation of this loop.

Example

Following is an example of the doseq statement.

(ns clojure.examples.hello
   (:gen-class))

;; This program displays Hello World
(defn Example []
   (doseq [n [0 1 2]]
   (println n)))
(Example)

In the above example, we are using the doseq statement to iterate through a sequence of values 0, 1, and 2 which is assigned to the variable n. For each iteration, we are just printing the value to the console.

Output

The above code produces the following output.

0
1
2
