JavaScript switch Statement

The switch statement is used to perform different actions based on different conditions. It is a great and more readable alternative to long if...else if...else structures when checking the same variable against multiple different values.

EXAMPLE

<!DOCTYPE html>
<html lang="en">
<body>
    <p id="switch-output"></p>

    <script>
        let day;
        // getDay() returns a number from 0 (Sunday) to 6 (Saturday)
        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";
                break;
            default:
                day = "Unknown day";
        }

        document.getElementById("switch-output").innerHTML = "Today is: <strong>" + day + "</strong>";
    </script>
</body>
</html>
