What is useEffectEvent and what problem does it solve?

React hooks and effects · Experienced

Model answer

In recent React versions, useEffectEvent lets you extract logic that reads the latest props or state inside an effect without making that value a dependency, so the effect does not re-run needlessly (for example, logging a visit with the current theme but only reconnecting when the room changes).

It is relatively new, so check the React documentation for the exact version and current status before relying on it.
