Enqueue the JS or CSS files using the wp_enqueue_script() or wp_enqueue_style() functions in the main plugin file.
Use the admin_enqueue_scripts hook to load scripts and styles in the WordPress admin area, and the wp_enqueue_scripts hook to load them in the frontend.
Utilize the wp_register_script() function to register the scripts with WordPress to ensure they are only loaded once.
Specify dependencies and version numbers for the enqueued scripts and styles to manage their loading order and prevent conflicts.
Use conditional tags to load the scripts and styles on specific pages or sections of the website if necessary.
Test the plugin to ensure that the JS and CSS files are being properly enqueued and loaded on the website.
