Check the active language

I'm sorry for my bad English. In my node.html.twig I have two layouts for two groups of languages.

1. English, Ukrainian and Bulgarian
2. Arabic, Farsi, Urdu I can't check with twig which is the active language to load one of the two layouts. I tried this but it didn't work. Thanks a lot if anyone can help me

{% if language.getId() == 'en' or 'uk' or 'bg' or 'ru' %}

    
        {{ content.field_mt_srv_body }}
        {{ content.field_sp_working_hours }}
        {{ content.field_sp_additional_information }}
        {{ content.field_mt_srv_video }}
    
    
         {{ content.field_sp_street_view }}
     
       

{{ content.field_sp_city }}

{{ content.field_sp_address }}

{{ content.field_sp_email }}

{{ content.field_field_sp_phone }}

{{ content.field_sp_languages }}

{{ content.field_mt_srv_tags }}

{{ content.field_sp_website }}

{{ content.field_sp_facebook }}

{% else %} {{ content.field_mt_srv_body }} {{ content.field_sp_working_hours }} {{ content.field_sp_additional_information }} {{ content.field_mt_srv_video }} {{ content.field_sp_street_view }} {{ content.field_sp_city }} {{ content.field_sp_address }} {{ content.field_sp_email }} {{ content.field_field_sp_phone }} {{ content.field_sp_languages }} {{ content.field_mt_srv_tags }} {{ content.field_sp_website }} {{ content.field_sp_facebook }} {% endif %}

To get this working in Twig

{% if language.getId() == 'en' or 'uk' or 'bg' or 'ru' %}

you have to define the variable language in a preprocess hook:

mytheme.theme or mymodule.module

/**
 * Implements hook_preprocess_HOOK() for node templates.
 */
function mytheme/mymodule_preprocess_node(&$variables) {
  $variables['language'] = \Drupal::languageManager()->getCurrentLanguage();
}

The only template where this variable is predefined is the page template, so that you don't need the preprocess hook. See this core preprocess hook: https://api.drupal.org/api/drupal/core%21includes%21theme.inc/function/template_preprocess_page/

In Drupal 8.5.7 and upwards a global variable 'language' exists that can be called directly in twig like example below.

{% if language == 'en' %}
