If your WordPress template is written in pure JS and the installed plugins work correctly without the connected jQuery library, then you can disable it – thereby improving the site loading speed.
Be careful disabling can lead to errors in the functioning of the site, make sure that your active scripts are not written on jQuery
To disable add in your theme function.php file code below:
function replace_jquery() {
if (!is_admin()) {
wp_deregister_script('jquery');
wp_register_script('jquery', 'https://code.jquery.com/jquery-3.6.0.min.js', array(), null, true);
wp_enqueue_script('jquery');
}
}
add_action('wp_enqueue_scripts', 'replace_jquery');
