You can use `try...catch` within the bodies of `componentDidMount` (in class components) and `useEffect` (in functional components) to handle errors that might occur during initialization or when fetching data. This is especially useful for handling asynchronous operations like API calls or database connections. Wrap the potentially error-prone code within a `try` block, and handle any exceptions in the `catch` block. This prevents errors from crashing the component and allows you to display appropriate error messages to the user or take corrective actions.
