How to effectively use WebSockets in a React application?

To effectively use WebSockets in a React application, start by choosing a robust WebSocket library like Socket.IO. This library simplifies WebSocket communication and handles reconnects and broadcasting efficiently. In your React components, establish the WebSocket connection in the `componentDidMount` lifecycle method (or `useEffect` hook for functional components).

Ensure to close the WebSocket connection in the `componentWillUnmount` method to prevent memory leaks. Manage the state of WebSocket data using React's state management or libraries like Redux. Also, consider implementing fallbacks for clients where WebSockets are not supported.
