What potential issues can arise when using JavaScript instead of PHP headers for redirection in web development?

One potential issue that can arise when using JavaScript instead of PHP headers for redirection is that search engine crawlers may not follow JavaScript redirects, affecting SEO. To solve this, you can use PHP headers to perform server-side redirection, ensuring that search engines and users are properly redirected.

<?php
header("Location: https://www.example.com/new-page.php");
exit();
?>
