What are the advantages and disadvantages of using JavaScript versus PHP header for page redirection and updates?

When it comes to page redirection and updates, using JavaScript allows for more dynamic and interactive user experiences, as it can be executed without reloading the entire page. On the other hand, PHP header redirection is more efficient in terms of server-side processing and can prevent certain security vulnerabilities such as clickjacking.

<?php
// Redirect to a new page using PHP header
header("Location: newpage.php");
exit();
?>
