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

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

Challenge: Record Collection

Link to the challenge:

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"

Thanks a lot. it works well now. my mistake was using “track” in place of “tracks”.
thanks again
