Using Drupal 8 entity query I’m trying to figure how I can fetch values from a specific content type and group them that are associated via a specific taxonomy term.

As seen in the screenshot below I have an entity field called Group Schedule that is currently binded to a Taxonomy Term. Is there way I could group those entities that are assigned to a specific taxonomy?

Group Schedule Name (field_group_sched) First Schedule (field_created_date) Second Schedule (field_created_date) 

So far I’ve managed to fetch the values from the Schedule Content type

// Entity Query for Schedule Node Type $  scheduleType = $  query->get('node')     ->condition('status', 1, '=')     ->condition('type', 'schedule')     ->condition('field_associated_programs', $  nid_degree, '=')     ->sort('created')     ->execute();  foreach ($  scheduleType as $  key => $  program) {      $  programNode = _nodeLoad($  program);      $  variables['schedule_content'][$  key]['schedule_group'] = $  programNode->get('field_group_sched')->value;     $  variables['schedule_content'][$  key]['schedule_name'] = $  programNode->get('field_schedule_name')->value;     $  variables['schedule_content'][$  key]['schedule_date'] = $  programNode->get('field_created_date')->value;   } 

{% for program in schedule_content %}  <div class="scheduled-dates">     <h3 class="label">{{ program['schedule_group'] }}</h3>     <span data-label="{{ program['schedule_name'] }}"  class="date" >{{ program['schedule_date'] }}</span>     </div>   {% endfor %}
