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

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

Link to the challenge:

Your solution is not adhering to the following rule.

If value is empty (""), delete the given prop property from the album.

After the 3rd test updateRecords(2548, “artist”, “”) runs, your solution should be deleting the “artist” property from the album. Your solution currently has no logic which would delete a property if val is “” and prop is NOT “tracks”.
