It is used to perform different actions on different conditions.
How does it works??
– switch expression is classified once & value of expression is compared with values of each case. The associated block of code is executed if there’s a match.
<!DOCTYPE html>
<html>
<body>
<p id="ex"></p>
<script>
var day;
switch (new Date().getDay()) {
case 0:
day = "Sunday";
break;
case 1:
day = "Monday";
break;
case 2:
day = "Tuesday";
break;
case 3:
day = "Wednesday";
break;
case 4:
day = "Thursday";
break;
case 5:
day = "Friday";
break;
case 6:
day = "Saturday";
}
document.getElementById("ex").innerHTML = "Today Is " + day;
</script>
</body>
</html>
Output :
