index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
</head>
<body>
    <pre id="output"></pre>
    <script>
        var inputArr = ['banana', 'mango', 'apple'];
        displayOutput = 'Input Array    : ' + inputArr;

        var reversedArr = inputArr.reverse();
        displayOutput += '\nReversed Array : ' + reversedArr;

        document.getElementById("output").innerHTML = displayOutput;
    </script>
</body>
</html>
