How do error boundaries handle errors in asynchronous code

1. Error Boundaries and Asynchronous Code:
- Error boundaries can catch errors that occur during asynchronous operations, such as network requests or setTimeout callbacks. This ensures that errors are handled correctly and do not crash the entire application.

2. Example Usage:
- Here is an example of how you can use an error boundary to handle errors in asynchronous code:

jsx
import { cache } from 'react-cache';
import { ErrorBoundary } from 'react';

const fetchData = cache((id) => {
  // Fetch the data from the server
  return fetch(`https://example.com/data/${id}`)
    .then((response) => response.json())
    .catch((error) => {
      // Cache the error
      return Promise.reject(error);
    });
});

function MyComponent({ id }) {
  const [data, setData] = useState(null);

  useEffect(() => {
    fetchData(id).then((data) => setData(data)).catch((error) => {
      // Handle the error
      console.error('Error fetching data:', error);
    });
  }, [id]);

  return (
    <ErrorBoundary fallback={<div>Error: {data}</div>}>
      {data ? (
        <p>Data: {data}</p>
      ) : (
        <p>Error: {data}</p>
      )}
    </ErrorBoundary>
  );
}
