    Basic Example
    This would check if the script named ‘fluidVids.js’ is enqueued. If it is enqueued, it does nothing. If it is not enqueued, the files are then registered and enqueued. 

    $handle = 'fluidVids.js';
$list = 'enqueued';
if (wp_script_is( $handle, $list )) {
    return;
} else {
    wp_register_script( 'fluidVids.js', plugin_dir_url(__FILE__).'js/fluidvids.min.js');
    wp_enqueue_script( 'fluidVids.js' );
}
