Error Handling in Async Code

What error handling pattern is demonstrated in this code?

try {
  await asyncOperation();
} catch (error) {
  if (error instanceof NetworkError) {
    // Handle network error
  } else if (error instanceof ValidationError) {
    // Handle validation error
  } else {
    throw error; // Re-throw unknown errors
  }
}

Generic error catching
Error type discrimination
This demonstrates error type discrimination pattern: 1) Different error types are handled differently, 2) Uses instanceof to check error types, 3) Provides specific handling for known error types, 4) Unknown errors are re-thrown for upper-level handling, 5) Maintains proper error handling chain, 6) Common pattern in service layers and API calls where different error types need different responses.
