Describe your issue in detail here.

i’ve looked through my code but can’t seem to figure out what i am missing

  **Your code so far**
// Setup
const recordCollection = {
2548: {
  albumTitle: 'Slippery When Wet',
  artist: 'Bon Jovi',
  tracks: ['Let It Rock', 'You Give Love a Bad Name']
},
2468: {
  albumTitle: '1999',
  artist: 'Prince',
  tracks: ['1999', 'Little Red Corvette']
},
1245: {
  artist: 'Robert Palmer',
  tracks: []
},
5439: {
  albumTitle: 'ABBA Gold'
}
};

// 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")){
  records[id][prop].add(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');
