질문할 것은 113열의

if(status == false){
    let check = document.querySelectorAll('.mybox > li > h2');

    let button = document.querySelectorAll('.mybox > li > buttion')

    check[i].style.textDecoration = "line-through";
    button[i].style.display = "none";
    /* 테스트를 위해 기본값 false로 실험 차후 완료 button 만들시 staus값을 true 이후
    *  해당 위치 if(status==true)로 만들고 진행 */

}else{


}

이 부분이 작동되지 않아서 질문드립니다.

quertySelectorAll로 문서에서 element를 받아오면 Array로 리턴되서 혹시 이렇게 사용하는게 아닌가요 ㅜㅜ?
