흔히 이렇게 알고 있다
Express executes middlewares and route handlers in strict sequential order, preventing subsequent routes from running until preceding async middlewares complete and call next().
이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.
컨트랙트
- A downstream route handler is executed before a preceding async middleware completes if an earlier middleware calls next() twice.
- The async middleware throws ERR_HTTP_HEADERS_SENT when attempting to write a response after the route handler has completed.
