Exact difference between the wordpress address url and the site address url

I am currently fixing a wordpress theme that contains absolute URLs. Example:

$.preloadImages('/wp-content/themes/themeName/img/button.png');

Now I want to prefix the url with something like WP_HOME or WP_SITEURL but I don't know which one to choose. What is the exact difference? In other words, what is the scenario in which the two might differ?

I guess they correspond to the "wordpress address" and the "site address" in the settings. However, the explanation there does not help me.

home_url : Its your Home URL for your site.

site_url : Where your wordpress Core files are located.

For your use you can use site_url this will work for you.

href="<?php echo get_template_directory_uri(); ?>/img/button.png"

so use get_template_directory_uri()

DIFFERANCE

1. get_template_directory();

<?php echo get_template_directory(); ?>

Returns an absolute server path (eg: /home/user/public_html/wp-content/themes/my_theme), not a URI.

2.get_template_directory_uri ()

Retrieve theme directory URI.

www.example.com/wp-content/theme/themename/image/image.png

AS per your query. if its for plugin then use plugin_url or for theme get_template_directory_uri()

get_template_directory_uri() . '/js/custom-script.js'

Here are other functions.

SITE URL the site_url template tag retrieves the site url for the current site (where the WordPress core files reside) with the appropriate protocol, 'https' if is_ssl() and 'http' otherwise. If scheme is 'http' or 'https', is_ssl() is overridden.

Use this to get the "WordPress address" as defined in general settings. Use home_url() to get the "site address" as defined in general settings.

$url = site_url();
echo $url;

Output: http://www.example.com or http://www.example.com/wordpress

HOME URL

The home_url template tag retrieves the home URL for the current site, optionally with the $path argument appended. The function determines the appropriate protocol,

 $url = home_url();
echo $url;

Output: http://www.example.com

So mostly both are similar. not different. you cal also use / in both to get / in output.

BLOG INFO

There is another one is blog info 

function bloginfo( $show='' ) {
    echo get_bloginfo( $show, 'display' );
}
<?php bloginfo('url'); ?> it will also return blog url .

I would use neither. Use a function instead of a constant get_bloginfo('url'); or get_bloginfo('wpurl');. If you have your wp-content inside of the wordpress install it does not really matter (but I prefer the first).

Take a look at the following functions: content_url(), get_template_directory_uri() (for parent themes) or get_stylesheet_directory_uri() (for themes including child themes). When using these functions you don't rely on one particular directory structure.

In your case I'd use

trailingslashit(get_stylesheet_directory_uri()) . 'img/button.png';

EDIT

WP_SITEURL is your WordPress address (wp_url) and WP_HOME is your blog address (url). By default the wp-content directory is a sibling to wp-admin and wp-includes and both constants have the same value but you move it out of there and make use of the WP_CONTENT_FOLDERNAME, WP_CONTENT_DIR and WP_CONTENT_URL constant to move it somewhere else, e.g.

wp-content
index.php
wordpress
  |-- wp-admin
  |-- wp-includes

now WP_SITEURL will return https://yourdomain.com/wordpress/ and WP_HOME will be https://yourdomain.com/, see https://codex.wordpress.org/Giving_WordPress_Its_Own_Directory for more details of giving WordPress its own directory.
