Output of loop with continue

What is the output of the following code?

Javascript

let result = '';
for (let i = 0; i < 5; i++) {
  if (i === 2) continue;
  result += i;
}
console.log(result);

A "01234"

B "024"

C "1234"

D "0134"

💡 Hint

The continue statement skips the current loop iteration when i equals 2.

The loop adds numbers 0 to 4 to the string except when i is 2, which is skipped by continue. So the output is "0134".

Continue in while loop output

What will be logged by this code?

Javascript

let count = 0;
let output = '';
while (count < 5) {
  count++;
  if (count === 3) continue;
  output += count;
}
console.log(output);

A "12345"

B "1245"

C "1234"

D "124"

💡 Hint

The continue skips adding when count is 3.

The loop increments count from 1 to 5. When count is 3, continue skips adding it to output. So output is '1' + '2' + '4' + '5' = '1245'.

Continue with nested loops output

What is the output of this nested loop code?

Javascript

let result = '';
for (let i = 1; i <= 3; i++) {
  for (let j = 1; j <= 3; j++) {
    if (j === 2) continue;
    result += `${i}${j} `;
  }
}
console.log(result.trim());

A "11 13 21 23 31 33"

B "12 13 22 23 32 33"

C "11 12 13 21 22 23 31 32 33"

D "11 13 22 23 31 33"

💡 Hint

The continue skips inner loop when j equals 2.

For each i, j runs 1 to 3. When j is 2, continue skips adding. So pairs with j=2 are skipped. Result is '11 13 21 23 31 33'.

Continue in forEach callback

What will this code output?

Javascript

const arr = [1, 2, 3, 4];
let sum = 0;
arr.forEach(num => {
  if (num === 3) continue;
  sum += num;
});
console.log(sum);

A 10

B 7

C SyntaxError

D TypeError

💡 Hint

continue cannot be used inside forEach callback.

The continue statement is invalid inside a forEach callback function and causes a SyntaxError.

Effect of continue on loop variable

Consider this code snippet. What is the final value of i after the loop ends?

Javascript

let i = 0;
while (i < 5) {
  i++;
  if (i === 3) continue;
  i++;
}
console.log(i);

A 5

B 6

C 8

D 7

💡 Hint

Notice how continue skips the second increment when i is 3.

The loop increments i twice each iteration except when i is 3, where continue skips the second increment. The final i is 5.
