How to create a class in js with auto callable method like __construct() in php?

Question

JavaScript

Let's say I want to make a Module class that will inherit the TestModule child class, which will have a run method that should be automatically called when an instance of the class is created.
In php I would do this:

class Module {
           public function __construct() {
               $this->run();
           }
       }
       
       class TestModule extends Module {
           public function run() {
               echo 'I`m TestModule';
           }
       }
       
       (new TestModule());
