How does the break statement work in JavaScript?

Can you explain how the break statement works in JavaScript?

Sure! The break statement is used to exit a loop or switch statement prematurely.

Can you give me an example of using break in a loop?

Of course! In a for loop, if you want to stop the loop when a certain condition is met, you can use break. For example:

for (let i = 0; i < 10; i++) {
    if (i === 5) {
        break;
    }
    console.log(i);
}

This will log numbers 0 to 4 and then exit the loop when i equals 5.

What happens if I use break in a nested loop?

Using break in a nested loop will only exit the innermost loop. If you want to break out of outer loops, you can use labeled statements.

Can you show me how to use labeled statements with break?

Certainly! Here's an example:

outerLoop: for (let i = 0; i < 3; i++) {
    for (let j = 0; j < 3; j++) {
        if (j === 1) {
            break outerLoop;
        }
        console.log(`i: ${i}, j: ${j}`);
    }
}

This will break out of the outer loop when j equals 1.
