Question about how <?php wp_footer(); ?> works

In the video, the navigation bar does not appear unless <?php wp_footer(); ?> is added.

My question is, where does wp_footer link to? I assumed that calls the wp_enqueue_script() from function.php, but if I comment out 

            wp_enqueue_script('modernizr_js', get_template_directory_uri() . '/js/modernizr.js', '', '', false); //we don't want it to appear in footer
            wp_enqueue_script('foundation_js', get_template_directory_uri() . '/js/foundation.js', array('jquery'), '', true); //foundation is DEPENDENT on jquery, we want this at footer
            wp_enqueue_script('main_js', get_template_directory_uri() . '/js/app.js', array('jquery', 'foundation_js'), '', true); //foundation is DEPENDENT on jquery, we want this at footer

from function.php, I can still see the navigation bar. So what exactly is wp_footer calling?

Thanks!

Just looking back at the question, I think I may have got "menu" mixed up with navigation. Is the wordpress menu the only thing this function would call?

Hey Rocket Alpaca,

The wp_head() and wp_footer() functions are added to the head and footer section of your theme template respectively. I suggest you open up /wp-includes/default-filters.php in your text editor, you will notice a //Actions section that includes the default actions. These default actions will be invoked when these functions are invoked. Below is an excerpt of code from default-filters.php :

add_action( 'wp_head', '_wp_render_title_tag', 1 );
add_action( 'wp_head',  'wp_enqueue_scripts', 1 );
add_action( 'wp_head',  'feed_links', 2);

You can see the some of the defaults for the wp_head() function that exist inb the WordPress core. hope this helps!
