How can I gracefully handle errors within a `useEffect` hook that performs asynchronous operations (e.g., API calls)?

When using `useEffect` for asynchronous operations, use a `try...catch` block within the effect function to catch potential errors. Then, within the `catch` block, implement error handling logic such as displaying an error message to the user, logging the error, or setting an error state variable to trigger UI updates. Consider using a state variable to manage the error state, enabling conditional rendering of error messages or fallback UI. Remember to clean up any pending requests in the `useEffect`'s cleanup function to avoid further issues after an error occurs.
