# What are label statements in JavaScript?

JavaScript label statements are used to prefix a label to an identifier. A label can be used with break and continue statement to control the flow more precisely. A label is simply an identifier followed by a colon (:) that is applied to a statement or a block of code. We will see two different examples to understand how to use labels with break and continue.

## Example

You can try to run the following code to use labels to control the flow, with break statement

Live Demo

<html>
<body>
<script>
document.write("Entering the loop!<br /> ");

outerloop: // This is the label name
for (var i = 0; i < 5; i++) {
document.write("Outerloop: " + i + "<br />");

innerloop:
for (var j = 0; j < 5; j++) {
if (j > 3 ) break ; // Quit the innermost loop
if (i == 2) break innerloop; // Do the same thing
if (i == 4) break outerloop; // Quit the outer loop
document.write("Innerloop: " + j + " <br />");
}
}
document.write("Exiting the loop!<br /> ");
</script>
</body>
</html>

## Example

You can try to run the following code to use labels to control the flow, with continue statement

Live Demo

<html>
<body>
<script>
document.write("Entering the loop!<br /> ");

outerloop: // This is the label name
for (var i = 0; i < 3; i++) {
document.write("Outerloop: " + i + "<br />");
for (var j = 0; j < 5; j++) {
if (j == 3) {
continue outerloop;
}
document.write("Innerloop: " + j + "<br />");
}
}
document.write("Exiting the loop!<br /> ");
</script>
</body>
