You should be able to load it like so:
Joomla\CMS\HTML\HTMLHelper::_('jquery.framework'); Else, if you're using Joomla's Web Asset Manager, then you can define it as a dependency in your JSON object:
{ "name": "foobar", "type": "script", "uri": "com_mycomponent/script.min.js", "dependencies": [ "jquery" ] }, 
Lodder answer is certainly useful, but not what I wanted to see. The correct loading of the embedded jquery looks like this.
use Joomla\CMS\Factory; $wa = Factory::getApplication()->getDocument()->getWebAssetManager(); $wa->useScript('jquery'); This will work if jquery has not been loaded before.
