How to break from a (for,while)loop in JavaScript

Home » javascript » How to break from a (for,while)loop in JavaScript

In this tutorial, we are going to learn about how to break from a for loop and while loop with the help of break statement in JavaScript.

In JavaScript, the break statement is used to stop/ terminates the loop early.

Breaking For loop

const arr = [1,2,3,4,5,6];

for(let i=0;i<arr.length; i++){

   if(i === 3){
     break; // breaks the loop after 4 iterations
-> output

In the above code, we iterate through the first 4 elements present in the array. after the 4 iterations, we are breaking the loop by using the break statement.

Breaking While loop

const arr = [1,2,3,4,5,6];

let i = 0;

while(i < arr.length){

   if(i === 4){
     break; // breaks the loop after 5 iterations


In the above, we are breaking the while loop after 5 iterations.
