CustomEvent: initCustomEvent() method
Available in workers
The CustomEvent.initCustomEvent() method initializes a CustomEvent object.
If the event has already been dispatched, this method does nothing.
Events initialized in this way must have been created with the createEvent() method.
This method must be called to set the event before it is dispatched using dispatchEvent().
Once dispatched, it doesn’t do anything anymore.
[!NOTE] Do not use this method anymore, as it is deprecated.
Rather than using the feature, instead use specific event constructors, like
CustomEvent(). The section on Creating and dispatching events gives more information about the way to use those.
