<div>이 부분에 <span style="color: #9cdcfe;">item</span>[<span style="color: #ce9178;">'id'</span>].<span style="color: #dcdcaa;">toString</span>() 이게 없다고 에러가 났었 거든요..</div>
<div>그래서 파이어베이스에 데이터베이스에 보니깐 id 컬럼이 없더라구요..</div>
<div>그래서 그걸 추가 하니깐 해결이 되기는 햇는데, 강의내용에는 id 컬럼을 추가를 하는 부분이 나오지</div>
<div>않은거 같아서 제가 문의를 드린 겁니다.</div>
<div>답변 감사합니다 . ㅎㅎㅎ</div>
