difference between wp_footer and get_footer
The get_footer() is a function which is used to include a theme file from theme directory. And wp_footer() is an action hook, which can be used as do_action( ‘wp_footer’ ) to inject scripts in the site HTML footer.
get_footer() is a custom html code which is available in footer.php and wp_footer() brings all the default code which is not only related to html but some functionality expected such as admin bar in top when you are logged in fron wp-admin.
