Let’s review what you learned in this lab about registering and unregistering callbacks for both static and object methods. You looked into WordPress Core and saw that it is using
call_user_func_array to call each of the registered callbacks for a given event hook. You learned strategies for working with 3rd party code including WooCommerce.
If the WordPress Event registrations confused you, go take this lab.
