Can you give a use case where this is needed?

We create a geocoding control and would like it to fire some events. I think it whouls do it the Maplibre way (extend Evented and implement IControl (which is just a TS type)).

Class Evened#fire method accepts Event or string. For us string is insufficient as we also want to provide event details.

I actually though about replacing evented class with eventemmiter library in some point,
But I don't mind adding it anyway.

Thanks.

eventemitter3 on npm doesn't seem to be actively developed. Maybe browser-native EventTarget. Also nanoevents looks good. In any case I think that extending from even-related class is antipattern. In my case, the MaplibreGeocodingControl control itself extends from GeocodingCotrolBase class where GeocodingCotrolBase is library agnostic and is used also for extending by Leaflet control implementation and so it can't extend from Maplibre Evented. I had to use ugly mixins.

[HarelM]

Yeah, I agree...
