Result:

rpayanm

<?php

// LOAD
// You can load up the menu tree with MenuLinkTree::load, which will give you an array of menu links to work with. From there it's just a matter of looping through and getting what you need, e.g.
$tree = \Drupal::menuTree()->load('main', new \Drupal\Core\Menu\MenuTreeParameters());
foreach ($tree as $item) {
  $title = $item->link->getTitle();
  $url_obj = $item->link->getUrlObject();
  $has_children = $item->hasChildren;
  // etc...

EntityQuery Conditions

The EntityQuery class can be loaded manually (if you know the entity type):

$query = \Drupal::service('entity_type.manager')->getStorage('node')->getQuery();

public function condition($field, $value = NULL, $operator = NULL, $langcode = NULL);

The $operator can take one of several options see core/lib/Drupal/Core/Entity/Query/QueryInterface.php::condition

rpayanm

<?php

// node, block, block_content, user, view, fiel, taxonomy_term, menu, menu_link_content, migration, ...
$storage = 'block';
$service = \Drupal::service('entity_type.manager')->getStorage($storage);

// LOAD
// One entity
$entity = $service->load($id);
