function template_preprocess_node

Prepares variables for node templates.

Default template: node.html.twig.

Most themes utilize their own copy of node.html.twig. The default is located inside "/core/modules/node/templates/node.html.twig". Look in there for the full list of variables.

Parameters

array $variables: An associative array containing:

• elements: An array of elements to display in view mode.
• node: The node object.
• view_mode: View mode; e.g., 'full', 'teaser'...
