Hi, i struggle for hours with this challenge and now i only have one problem, it seems that my code doesn’t work when i need something as the first element, can someone help me?

Your code so far

// Setup
var collection = {
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(object, id, prop, value) {
if(value == ""){
  delete object[id][prop];
}else if(prop != "tracks"){
    object[id][prop] = value;
}else if(object.hasOwnProperty("tracks")){
  object[id][prop] = [];
return object;

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