잘 하셨는데, 이 부분에서 조금 더 가독성을 높일 수 있는 방법을 알려드릴게요!
const VoteValue = {
UP: 1,
DOWN: -1,
};
을 위에 선언해주고, vote(1) 대신 vote(VoteValue.UP), vote(-1) 대신 vote(VoteValue.DOWN) 로 값을 입력해줄 수 있어요!
내가 짠 코드도 일주일만 지나면 이게 뭐였지 하는 경우가 많고, 타인과 협업을 할 때는 다른 사람의 코드를 읽을 때 숫자나 문자가 그대로 하드코딩 되어있으면 이해하는데 시간이 필요한 경우가 많아서 이렇게 원하는 값을 좀 더 직관적으로 랩핑해주면 훨씬 더 좋은 코드를 작성할 수 있습니다~!
