What are the advantages and disadvantages of using JavaScript versus PHP for handling navigation in a web application?

When deciding between using JavaScript or PHP for handling navigation in a web application, it's important to consider the advantages and disadvantages of each. JavaScript allows for dynamic and interactive navigation without needing to reload the entire page, providing a smoother user experience. However, PHP can handle server-side navigation more efficiently and securely, especially when dealing with sensitive data or authentication.

<?php
// PHP code for handling navigation in a web application
if(isset($_GET['page'])) {
    $page = $_GET['page'];
    include($page . '.php');
} else {
    include('home.php');
}
?>
