Loop Control in JavaScript: break and continue

JavaScript

JavaScript is the superhero of web development—powerful, flexible, and sometimes a little unpredictable, but without it, websites would be as boring as a blank Word document!

 

Loops are powerful, but sometimes they just need to chill. Enter break and continue, the ultimate loop managers. break stops the loop entirely, like rage-quitting a game. continue skips the current iteration and moves to the next one, like pretending you didn’t see that embarrassing typo.

1. break: The Escape Artist

When you use break, your loop just stops—no questions asked. It’s like realizing you’re in the wrong Zoom meeting and exiting immediately.

Example:

for (let i = 1; i <= 5; i++) {
  if (i === 3) {
    console.log("Breaking at 3! I'm out!");
    break;
  }
  console.log("Iteration " + i);
}

Output:

Iteration 1
Iteration 2
Breaking at 3! I'm out!

Real-life analogy: You walk into a party, see your ex, and leave immediately.

2. continue: The Selective Ignorer

The continue statement skips the current loop iteration and moves to the next one. It’s like scrolling past a spoiler without reading it.

Example:

for (let i = 1; i <= 5; i++) {
  if (i === 3) {
    console.log("Skipping 3! Not today!");
    continue;
  }
  console.log("Iteration " + i);
}

Output:

Iteration 1
Iteration 2
Skipping 3! Not today!
Iteration 4
Iteration 5

Real-life analogy: When you see veggies on your plate and just eat the fries. 

3. break vs continue: Spot the Difference 

Feature	break	continue
Stops the loop completely?	Yes	No
Skips just one iteration?	No	Yes
Common analogy	Rage quitting a game 🎮	Skipping a bad song on shuffle

4. break and continue in while Loops

These work the same way in while loops too!

Example:

let num = 0;
while (num < 5) {
  num++;
  if (num === 3) {
    console.log("Skipping 3 in while loop!");
    continue;
  }
  console.log("Number: " + num);
}

5. Be Careful! 

Overusing break and continue can make your code harder to read. Use them wisely—like a ninja, not a berserker. 

Conclusion

break and continue help control loops efficiently. break is your emergency exit, while continue is your selective skip button. Use them smartly to make your code cleaner and funnier!
