// 只修改这一行下面的代码
function updateRecords(records, id, prop, value) {
  if(value.length===0){
    delete records.prop;
    return records;
    }
  else if(prop!="tracks"&& !value.length===0){
    let prop=value;
    return records;
    }
  else if(prop="tracks"&& !value.length===0){
    let tracks="";
    tracks[length-1]=value;
    return records;
    }
    return records;
}

updateRecords(recordCollection, 5439, 'artist', 'ABBA');
