Limit JS loading on non directory pages

Hi,

We’re using this plugin and all working well – we would just like to optimise the site loading times and trying to find out if there is a function to check if we’re on a directory page (category or listing) so we can limit loading of the following file:

/wp-content/plugins/business-directory-categories/resources/categories-module.min.js

Which currently loads on all pages.

Ideally usage something like :

if(!is_wpbdp()) {
	wp_deregister_script( 'wpbdp-categories' );
}

As this is the format we are using to limit loading of other plugin scripts.

Many thanks in advance.
Sadie
