I am new to Drupal, but I am very familiar with WordPress.
In WordPress, I am able to hook into the head of a document with wp_head to add things like page specific meta tags.
When using a custom theme based on Stable, how would you add page specific things in the <head> of a document in Drupal 8?
Note: I am wondering how this would be done without a custom module.
You can attach the tag to the page's render array via hook_page_attachments_alter().
An example from the related change record:
function MYTHEME_page_attachments_alter(array &$page) {
$viewport = array(
'#type' => 'html_tag',
'#tag' => 'meta',
'#attributes' => array(
'name' => 'viewport',
'content' => 'width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no',
),
);
$page['#attached']['html_head'][] = [$viewport, 'viewport'];
}
$page and it looks like I have one key #attached with library, html_head_link, html_head as sub keys. Are there others that I could add?

#. The method that renders whatever element type the property is on decides what to do with it. It's better to approach it as "what do I need to do?" rather than "what are all the things I could do?", as it's basically infinite by nature
