function guyPrimaveraLoadScripts() {

    $cssPath = get_stylesheet_directory() . '/myStylesheet.css';

    wp_enqueue_style(
        'myStylesheet',
        get_stylesheet_directory_uri() . '/myStylesheet.css',
        array(),
        filemtime( $cssPath )
    );

    $jsPath = get_stylesheet_directory() . '/js/myJavaScript.js';

    wp_enqueue_script( 
        'myJavaScript', 
        get_stylesheet_directory_uri() . '/js/myJavaScript.js', 
        array ( 'jquery' ), 
        filemtime( $jsPath ),
