Resolver

^{ref / conversations / Resolver}

A resolver wraps a promise so that it can be resolved by an outside event. It is a container for two things:

• a promise which you can await
• a function resolve which you can call

Once you call resolve, the contained promise will resolve.

The status flag isResolved indicates if resolve has been called or not.
