// Setup
const recordCollection = {

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

updateRecords(recordCollection, 5439, 'artist', 'ABBA');
//console.log(recordCollection);```
