---------------
---------------
case n:
// code block
break;
default:
// code block
}
Example:
<html>
<body>
<script>
var val=12;
switch(val)
{
case 10:document.write("Smaller Value. It's 10");
break;
case 12:document.write("Exact Value Matched. It's 12");
break;
case 14:document.write("Larger Value. It's 14");
break;
default:document.write("Invalid");
}
</script>
</body>
</html>
Output of the preceding program is as follows:
The break Statement
JavaScript exits the switch block when it reaches the break keyword. This will bring the execution of the
switch block to a halt. The last case in a switch block does not need a break statement. In any case, the block
terminates there.
