    * Для общих ошибок со стороны клиента можно просто использовать код `400`.
* `5XX` – статус-коды, сообщающие о серверной ошибке. Они почти никогда не используются разработчиками напрямую. Когда что-то идет не так в какой-то части кода вашего приложения или на сервере, он автоматически вернёт один из 5XX кодов.

* **`4xx`** 상태 코드는 "클라이언트 오류" 응답을 위해 사용됩니다. 이것은 아마 가장 많이 사용하게 될 두번째 유형입니다.
    * 일례로 `404` 는 "찾을 수 없음" 응답을 위해 사용합니다.
    * 일반적인 클라이언트 오류의 경우 `400` 을 사용할 수 있습니다.
* `5xx` 상태 코드는 서버 오류에 사용됩니다. 이것들을 직접 사용할 일은 거의 없습니다. 응용 프로그램 코드나 서버의 일부에서 문제가 발생하면 자동으로 이들 상태 코드 중 하나를 반환합니다.
