Labeled break and continue in Javascript - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to break out of the outer loop using a label.

Javascript

outerLoop: for (let i = 0; i < 3; i++) {
  for (let j = 0; j < 3; j++) {
    if (i === 1 && j === 1) {
      [1] outerLoop;
    }
  }
}

💡 Hint

Common Mistakes

Using 'continue' instead of 'break' to exit the loop.

Forgetting to add the label after 'break'.

The 'break' statement with a label exits the labeled loop immediately.

2fill in blank

medium

Complete the code to continue the outer loop when a condition is met.

Javascript

outer: for (let i = 0; i < 3; i++) {
  for (let j = 0; j < 3; j++) {
    if (j === 1) {
      [1] outer;
    }
  }
}

💡 Hint

Common Mistakes

Using 'break' instead of 'continue' to skip iterations.

Not specifying the label after 'continue'.

The 'continue' statement with a label skips to the next iteration of the labeled loop.

3fill in blank

hard

Fix the error in the labeled continue statement.

Javascript

outerLoop: for (let i = 0; i < 2; i++) {
  for (let j = 0; j < 2; j++) {
    if (i === j) {
      [1] outerLoop;
    }
  }
}

💡 Hint

Common Mistakes

Misspelling 'continue' as 'continuee'.

Using 'break' when 'continue' is needed.

The correct keyword is 'continue' to skip to the next iteration of the labeled loop.

4fill in blank

hard

Fill both blanks to correctly use labeled break and continue in nested loops.

Javascript

outer: for (let i = 0; i < 3; i++) {
  inner: for (let j = 0; j < 3; j++) {
    if (i === 1 && j === 1) {
      [1] outer;
    }
    if (j === 2) {
      [2] inner;
    }
  }
}

💡 Hint

Common Mistakes

Mixing up 'break' and 'continue' keywords.

Using wrong labels or missing labels.

Use 'break outer;' to exit the outer loop and 'continue inner;' to skip to the next iteration of the inner loop.

5fill in blank

hard

Fill all three blanks to create a labeled loop that breaks and continues correctly.

Javascript

outerLoop: for (let i = 0; i < 4; i++) {
  innerLoop: for (let j = 0; j < 4; j++) {
    if (i === 2 && j === 2) {
      [1] outerLoop;
    }
    if (j === 3) {
      [2] innerLoop;
    }
    console.log(i, j);
  }
  if (i === 3) {
    [3];
  }
}

💡 Hint

Common Mistakes

Using 'break' without label to exit outer loop.

Using 'continue' without label to skip inner loop.

Confusing 'return' with 'break' or 'continue'.

Use 'break outerLoop;' to exit the outer loop, 'continue innerLoop;' to skip inner loop iterations, and 'return;' to exit the function.
