📖 이번 장에서 학습한 내용
매번 설계할때마다 '객체'를 먼저 고려했다.
단순히 이 '객체'가 어떤 상태를 가지고 어떤 메서드를 가질지 생각하고 판단했다.
하지만 이 방식이 잘못되었다는걸 느꼈다.
'객체'를 생각하기 전에 가장 먼저 '메시지'를 생각해야 하고 항상 '협력'이라는 문맥안에서 '객체'를 생각해야 한다.
'협력'안에서 어떤 '메시지'가 필요한가 ?
그리고 그 '메시지'를 가장 잘 표현할 수 있는, 상태를 소유한 '객체'는 누구인가 ?
🖥️ 프론트엔드 관점에서의 적용
CRC 카드를 만들어 보았다.
과거에 했던 미션에 적용해 보면서 책임에 비해 잘못된 상태나 행동을 가진 컴포넌트를 유추했다.
