I can't get my jquery to work in my wordpress site

I was told that jquery was automagically included in wordpress from the get go, but I went ahead and included jquery in my functions.php. I'm trying to do a simple script that scrolls down to a div#id when a link is clicked.

I created this script:

jQuery(document).ready(function($) {
  jQuery("#view-visibility").click(function() {
   JQuery('html, body').animate({
    scrollTop: jQuery("#visibility").offset().top
   }, 2000);
  });
)};

I put the script in my own file, script.js, and added it to the functions.php:

`

function theme_js() {
  //parameters: 1.handle, 2.path, 3.array of dependents, 4.version specification, 5.load in footer? true or false
  wp_enqueue_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js', '', '3.1.1', true );
  wp_enqueue_script( 'bootstrap_js', 'https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.4/js/bootstrap.min.js', array('jquery'), '', true );
  wp_enqueue_script( 'my_js', get_template_directory_uri . '/script.js', array('jquery'), '', true );

}

add_action( 'wp_enqueue_scripts', 'theme_js' );`

I still can't get it to work... I don't know what the deal is!! Should I be loading jquery in the head or before the body?
