A Brief example of using the "case" command:

<html>
<body>

<input id="myInput" type="text">
<button onclick="myFunction()">Enter a color</button>

<p id="demo"></p>

<script>
function myFunction() {
    var text;
    var colors = document.getElementById("myInput").value;

    switch(colors) {
        case "red":
            text = "Red is the color of the sky... On Mars!";
        break;
        case "blue":
        text = "Blue is the color of the sky on Earth.";
        break;
        case "green":
        text = "Green is the color of your nose.";
        break;
        default:
        text = "I have never heard of that color... Remember to use lower case. I'm not too bright.";
    }
    document.getElementById("demo").innerHTML = text;
}
</script>

</body>
</html>

Review! Using "if" and "else" logic control:

<html>

<body>

var answer = prompt('What has a neck, but no head? (One word answer.)');

if (answer === 'bottle') {

document.write("You cheated.") ;

} else {

document.write("You were so close!") ;

}

</script>

</body>

</html>
