Record Collection javascript //asking for another help

Tell us what’s happening:

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!=="empty"){
  }else if(prop ==="tracks"&& !collection[id].hasOwnProperty("tracks")){
    collection[id][prop]=[value]; //Is this line creating a new array with new value?? :create an empty array before adding the new value to the album's corresponding property.???
  }else if (prop ==="tracks"&& value !==""){
  }else if (value===""){
    delete collection[id][prop];

   return collection;



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