How do I print the variable "activeLangcode" in a paragraph twig template?

Question

I tried to get the value with (what didn't work):

{{ paragraph.activeLangcode }} {{ paragraph.activeLangcode.value }}

Answer 1

Get the language of the paragraph entity through the method language() in a preprocess hook:

function mytheme_preprocess_paragraph(&$variables) {
  $variables['lang_id'] = $variables['paragraph']->language()->getId();
}

For a Twig only solution you would need to adjust the twig sandbox policy, see Language name of translated node

Answer 2

Didn't work for me; So I used this method:

{% set language = content.field_title['#language'] %}
