Error Handling in Async Code

What error handling feature is demonstrated here?

async function* processStream(stream) {
  try {
    for await (const chunk of stream) {
      yield await processChunk(chunk);
    }
  } catch (error) {
    yield* handleStreamError(error);
  } finally {
    await stream.close();
  }
}

Basic error catching
Resource cleanup in finally block
This demonstrates proper resource cleanup using finally: 1) Ensures resources are released even if errors occur, 2) Handles both successful and error cases, 3) Prevents resource leaks in async iterators, 4) Follows the RAII (Resource Acquisition Is Initialization) pattern, 5) Critical for handling streams and connections properly, 6) Works with both sync and async cleanup operations.
