how to just print the value of author in node template There are some variables like author_name in node.html.twig of Drupal 8. {{ author_name }} will print something like below:

 &lt;div&gt;&lt;span&gt;&lt;span&gt;Basic&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;


I tried using codes like below:

{{ author_name.0 }} plan to print: Basic

or

{{ author_name|field_value }} plan to print: Basic


Above codes NOT work. How can I achieve above result?
For most cases How do I get the raw field value in a twig template? will do. But since here according to node.html.twig


  author_name: Themed author name field.


I believe you can get the unthemed author name by using {{ node.getOwner.getDisplayName }}
