Why in the template file variable's properties are get by dot (.) but added variables are get by arrow (->). In mainmenu.tpl I have:

public function renderWidget($hookName, array $configuration)
{

    $this->smarty->assign([
        'menu' => $this->getWidgetVariables($hookName, $configuration),
    ]);
    
    // assign new variable
    $id = 661;
    $id_lang = $this->context->language->id;
    $product = new Product((int) $id, false, (int) $id_lang);
    $this->smarty->assign('product', $product);

    return $this->fetch('module:ps_mainmenu/ps_mainmenu.tpl');
}

and in ps_mainmenu.tpl:

    {$menu.label}
    {$product->name}
    {$product.name} //not render

How to acccess every property by dot?

The (.) accessor is used when referencing properties of associative array, and in this type are passed most of prestashop objects. So object should be casted to array:

$this->smarty->assign('product', (array)$product);
