Record Collection | I don't know how to push values in array or make an array in object

Tell us what’s happening:
I am trying to solve this problem but I don’t know the way how to make an aaray in object. Although, I can make object with key value but I don’t know how to make an array.

Your code so far

// Setup
var collection = {
    "2548": {
      "album": "Slippery When Wet",
      "artist": "Bon Jovi",
      "tracks": [ 
        "Let It Rock", 
        "You Give Love a Bad Name" 
    "2468": {
      "album": "1999",
      "artist": "Prince",
      "tracks": [ 
        "Little Red Corvette" 
    "1245": {
      "artist": "Robert Palmer",
      "tracks": [ ]
    "5439": {
      "album": "ABBA Gold"
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) {

  if (prop != "tracks" && value !="" ){
    collection[id][prop] = value;
  return collection;

// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
