// Only change code below this line
function updateRecords(object, id, prop, value) {
if(prop !=="track" && value!=="")
else if(prop === "track" && !object[id].hasOwnProperty("track"))
else if(prop ==="track" && value!=="")
else if(value ==="")
  delete object[id][prop];
return object;

updateRecords(collection, 5439, 'artist', 'ABBA');
//updateRecords(collection, 5439, 'tracks', ['Take a Chance on Me']);

what happens if there is not alreay a tracks property? push needs an array to work

edit: you always use track, it should be "tracks"
