Hogyan lehet a jelenlegi nyelven a Drupal 8

To get all enabled language in drupal 8 :

 \Drupal::languageManager()->getLanguages();

This may be helpful to any one.

Drupal 7:

global $language;
// return lang code;
return $language->language;

Drupal 8:

return $language = \Drupal::languageManager()->getCurrentLanguage()->getId();

Thanks its work for me :)
