Core Drupal8 JS necessary for Drupal theme to function I have recently noticed that Drupal8 is adding number of JavaScript files. I would like to know if it is necessary for theme to function

&lt;script src="/core/assets/vendor/domready/ready.min.js?v=1.0.8"&gt;&lt;/script&gt;
&lt;script src="/core/assets/vendor/jquery/jquery.min.js?v=2.2.4"&gt;&lt;/script&gt;
&lt;script src="/core/misc/drupalSettingsLoader.js?v=8.3.7"&gt;&lt;/script&gt;
&lt;script src="/core/misc/drupal.js?v=8.3.7"&gt;&lt;/script&gt;
&lt;script src="/core/misc/drupal.init.js?v=8.3.7"&gt;&lt;/script&gt;


My theme does not use any of them. I would like them to be removed. Can anyone here tell me how to remove them?
In your .info.yml file specify:

libraries-override:
  core/drupal.active-link: false

You may have to remove more libraries, but this one is specifically for the files you mentioned.
