3. 11.x core/lib/Drupal/Core/Render/PlaceholderGeneratorInterface.php \Drupal\Core\Render\PlaceholderGeneratorInterface::createPlaceholder()

Turns the given element into a placeholder.

Placeholdering allows us to avoid "poor cacheability contamination": this maps the current render array to one that only has #markup and #attached, and #attached contains a placeholder with this element's prior cacheability metadata. In other words: this placeholder is perfectly cacheable, the placeholder replacement logic effectively cordons off poor cacheability.

Parameters

Return value

array Render array with placeholder markup and the attached placeholder replacement metadata.
