render(&$element)
Renders an element.
This function renders an element. The top level element is shown with show() before rendering, so it will always be rendered even if hide() had been previously used on it.
Parameters
$element: The element to be rendered.
Return value
The rendered element.

function render(&$element) {
if (!$element && $element !== 0) {

}
if (is_array($element)) {
// Early return if this element was pre-rendered (no need to re-render).
if (isset($element['#printed']) && $element['#printed'] == TRUE && isset($element['#markup']) && strlen($element['#markup']) > 0) {
return $element['#markup'];
}
show($element);
return \Drupal::service('renderer')->render($element);
}
else {
// Safe-guard for inappropriate use of render() on flat variables: return
// the variable as-is.
return $element;
