![]() In this tutorial, we explained the while and do.while loops used in the JavaScript. ![]() Let's take an example and see the do.while loop in action. for/in - loops through the properties of an object. While(condition) JavaScript do.while Loop: Example JavaScript supports different kinds of loops: for - loops through a block of code a number of times. So, even if the condition is true or false, the code block will be executed for at least one time.īelow we have the syntax of the do.while loop, do In the do-while loop, the condition is checked after executing the loop. Just like the while loop, the do.while loop lets you iterate the code block as long as the specified condition is true. In this example, we are using while loop, and the loop executes only if the specified condition is true. Let's take an example to see the while loop in action. JavaScript while Loop: Syntax and Useīelow is the syntax for the while loop: while(condition) The only difference between the while loop and do.while loop is that the do.while loop will execute at least once because in do.while loop the condition is checked after execution of code block. Just like for Loop, the while and do.while loop are also used to execute code statements multiple times based on a condition. JavaScript while loop lets us iterate the code block as long as the specified condition is true. Whenever you want to execute a certain statement over and over again you can use the JavaScript while loop to ease up your work.
