The break is a keyword in JavaScript which is used for bringing the program control out of the loop. The break statement
halts the execution of a loop and program flow switches to the statement after the loop. A single break statement will
break out of only one loop.

The following example shows the use of break statement in a loop:
Example:
<HTML>
<BODY text="blue">
<H2 style="color:red;">Using a loop with a break statement.</H2>
<SCRIPT>
for(i=1;i<10;i++) {
if (i%3==0)
{ break; }
else {
document.write("The number is " + i + "<br> <br>"); }
}//for ends
document.write("Statement outside for loop");
</SCRIPT>
</BODY>
</HTML>
On running the above program, we get the following output:
Let us try to understand this example. The variable ‘i’ is initialised with the value 1. Since 1 is not divisible by 3, the if
condition turns out to be false and so the else block is executed—“The number is 1” is displayed on screen. The same
happens when i=2.
