Handling Errors with try-catch-finally

What error handling best practice is shown here?

function fetchData() {
  return fetch('/api/data')
    .catch(error => {
      throw new NetworkError('Failed to fetch data', { cause: error });
    });
}

try {
  await fetchData();
} catch (error) {
  if (error instanceof NetworkError) {
    // Handle network error
  }
}

Basic error catching
Error type enrichment
This shows error type enrichment: 1) Converts generic errors to specific types, 2) Maintains error cause chain, 3) Enables type-specific handling, 4) Improves error context, 5) Better for debugging and logging, 6) Common in API operations, 7) Enhances error handling capabilities, 8) Facilitates better error recovery.
