};

// Only change code below this line
function updateRecords(records, id, prop, value) {
if(prop!=="tracks"&&value!==""){
records[id][prop]=value;
}else if(prop==="tracks"&&records[id].hasOwnProperty("tracks")===false){
records[id][prop]===[value];
}else if(prop==="tracks"&&value!==""){
records[id][prop].push(value);
}else if(value===""){
delete records[id][prop];
}
return records;
}
updateRecords(recordCollection, 5439, "artist", "ABBA");
updateRecords(recordCollection,5439, "tracks", "Take a Chance on Me");
updateRecords(recordCollection, 2548, "artist", "");
