In this article, we would like to show you how to use the do...while statement in JavaScript.

Syntax

do {
  // statement
} while (condition);

Description

The do...while statement is used to create a loop that executes a specified block of code at least once, and then repeatedly executes the block until the test condition evaluates to false.

Practical example

In this example, the do...while loop iterates at least once and reiterates until i is no longer less than 3.

// ONLINE-RUNNER:browser;

let i = 0;

do {
  ++i;
  console.log(i);
} while (i < 3);

Output:

1
2
3
