Loop control with labels

Question

How to use the labels with break and continue to control loops?

Answer 1

Break statement terminates the loop directly.
Continue statement tells the program to go to the top of the loop and iterate its contents again.

Answer 2

A label can be used with break and continue 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.

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 /> ");

Output:

Entering the loop!
Outerloop: 0
Innerloop: 0
Innerloop: 1
Innerloop: 2
Innerloop: 3
Outerloop: 1
Innerloop: 0
Innerloop: 1
Innerloop: 2
Innerloop: 3
Outerloop: 2
Outerloop: 3
Innerloop: 0
Innerloop: 1
Innerloop: 2
Innerloop: 3
Outerloop: 4
Exiting the loop!
