+* [`useEffectEvent`](/reference/react/useEffectEvent) extracts non-reactive logic from your Effects into a reusable function.

+function ChatRoom({ roomId, theme }) {
+  const onConnected = useEffectEvent(() => {
+    showNotification('Connected!', theme);
+  });
+
+  useEffect(() => {
+    const connection = createConnection(serverUrl, roomId);
+    connection.on('connected', () => {

+    });
+    connection.connect();
+    return () => connection.disconnect();
+  }, [roomId]);

 These Hooks are mostly useful to library authors and aren't commonly used in the application code.
 
-- [`useDebugValue`](/reference/react/useDebugValue) lets you customize the label React DevTools displays for your custom Hook.
