store-event-handlers-in-refs

Storing event handlers in refs prevents unnecessary re-subscriptions in React effects by maintaining a stable reference to the latest handler. This ensures listeners are attached and detached correctly without performance penalties from frequent re-renders.

You can optimize React event handling by storing the latest handler in a `useRef` and updating it separately, then reading from that ref inside your `useEffect`. `useEffectEvent` also offers a cleaner modern approach for stable subscriptions.

The best way to manage stable event subscriptions in custom React hooks is utilizing `useRef` to hold the current handler reference. This separates listener attachment from handler updates, ensuring listeners remain stable across re-renders.

`useEffectEvent` works with custom React hooks by providing a cleaner approach to stable event listener management in modern React versions. It achieves the same ref-based handler isolation automatically, preventing re-subscriptions without manual ref updates.

You should use refs to store event handlers when your component requires stable event subscriptions within effects but experiences performance issues from frequent re-renders. This pattern prevents re-attaching listeners when only the callback logic changes.
