In this tutorial, you will learn how you can break out of the Array.foreach() method in JavaScript


The break statement is being used to stop a for loop or a for...of loop in JavaScript.


const array = [1,2,3,4,5];
for(let i=0; i<array.length; i++) {
  if (i>=3) {
    break;
  }
  console.log(array[i])
}
// 1
// 2
// 3


However, the break statement does not work inside the foreach because of the callback function, it throws Uncaught SyntaxError: Illegal break statement error


const array = [1,2,3,4,5];
array.forEach(num=>{
  if (num >= 3) {
    break;
  };
  console.log(num)
})

// Uncaught SyntaxError: Illegal break statement


To break out of the forEach() method we have to write the return statement instead of the break statement.


const array = [1,2,3,4,5];
array.forEach(num=>{
  if (num >= 3) {
    return;
  };
  console.log(num)
})
// 1
// 2
