🥁 누른 키의 audio와 key element 찾기 >HTML을 먼저 살펴보자. HTML data-key속성으로 숫자가 쓰여있는 것을 볼 수 있다. 이 숫자의 의미는 무엇일까? 🎵 keyCode 자바스크립트에서 키보드 이벤트를 받았을 때 키 값을 구별할 수 있는 코드이다. >keyCode목록을 확인해보고 싶다면 참고: https://blog.outsider.ne.kr/322 https://keycode.info/ 에서도 누른 키의 keyCode를 바로바로 확인해볼 수 있다. (아래 이미지 참고) >자, data-key로 keyCode를 설정해두었다는 것을 알 수 있다. 키보드를 누를때마다 해당하는 키에 이벤트를 등록해야 하기 떄문이다.
