Javascript and Stylesheet in child page

This code will check to make sure that the Our People page is being viewed (page with slug our-people) or one of the children of page with ID 597, and will enqueue both the JavaScript and CSS if so:

function wpse241030_scripts() {
    // Bail if we're not looking at the Our People page or one of the children of page with ID 597.
    if ( ! is_page( 'our-people' ) && ! in_array( 597, (array) get_post_ancestors( get_the_ID() ) ) ) {
        return;
    }

    // Enqueue unslider JS
    wp_enqueue_script( 'unslider-js', get_stylesheet_directory_uri() . '/library/js/unslider-min.js', array( 'jquery' ), '1', false );

    // Enqueue unslider CSS
    wp_enqueue_style( 'unslider-css', get_stylesheet_directory_uri() . '/library/css/unslider.css', array(), '', 'all' );
}
add_action( 'wp_enqueue_scripts', 'wpse241030_scripts' );
