The `langCode.html` partial template is added to the `layouts/partials/function` directory. This template is used to check if the current language code matches the site's language code. It iterates over the language codes and sets a boolean variable `$res` to `true` if there is a match. The template then returns the value of `$res`. This partial template can be used in other templates to conditionally render content based on the language code.
The currentMenuItem.html template partial is added to the layouts/partials/function directory. This partial is used to retrieve the current menu item based on the current page URL. It iterates through the main menu items defined in the site configuration and compares the URL of each menu item with the URL of the current page. If a match is found, the name and ID of the menu item are stored in variables. Finally, a dictionary containing the name and ID is returned. This partial can be used to highlight the current menu item in the navigation menu.
