Should I wait for the broker.broadcast => Promise<void>?

Hello,

I was wondering what is the difference if I do

void broker.broadcast(...)

and

await broker.broadcast(...)

The same question would be valid for emit method.

Personally, I don't see any reason to await the event response unless for some reason you don't wish to proceed with the rest of the execution flow until it returns. In our project, we use broker.broadcast(...).catch((err) => { ... log error ... }); so we can fire-and-forget the events but if there happens to be an error it gets logged. We don't want it to throw in that case.

I see. It uses the promise to leverage the error callback functionality then.
Should it just be a callback parameter then to avoid the doubt about the promise per se? I mean, since the promise result itself would not bring any value.
