Question 6/97

Since Aura application events follow the traditional publish-subscribe model, which method is used to fire an event?

A. ernit()

B. fireEvent()

C. fire()

D. registerEvent()

Correct Answer: C

The fire() method is used to fire an Aura application event from a component controller or helper. This method takes the event instance as a parameter and broadcasts it to all components that are listening for that event type. The registerEvent() method is used to declare an event in a component markup, not to fire it.
The emit() and fireEvent() methods are not valid methods for Aura application events. References:
