The JavaScript break and continue statements are very important. The break statement is used to terminate or jump out of a loop and the continue statement is used to skip one iteration or jump over one iteration in the loop. Following are explanations of JavaScript Break and Continue with an example:
The Break Statement
The Break statement is used to terminate a loop or jump out of a loop.
<!DOCTYPE html>
<html>
<body>
<script>
for (let i = 1; i < 8; i++) {
if (i === 6) { break; }
document.write("Iteration # " + i + "<br>");
}
</script>
</body>
</html>
Output:
In the example above, the break statement ends the loop when the loop counter is n == 6.
The Continue Statement
If a specified condition arrived in the code, the continue statement skips one iteration and may continue with the next iteration in the loop.
<!DOCTYPE html>
<html>
<body>
<script>
for (let i = 1; i < 12; i++) {
if (i === 6) { continue; }
document.write("Iteration # " + i + "<br>");
}
</script>
</body>
</html>
Output:
The above example skips the value of 6:
