Record Collection 2nd test failing

Tell us what’s happening:

The second test case is coming back as failing, but can’t figure out what is wrong with my code. Any help would be awesome.

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 !== "") {
    if (collection[id][prop]) {
    else {
      collection[id][prop] = value;
  else if (value !== "") {
    collection[id][prop] = value;
  else if (value === "") {
    delete collection[id][prop];
  return collection;

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

You are very close.

Consider how tracks are supposed to be stored in this object. Look at how you have added tracks from other test cases.

Then consider how your code is storing the track from that test case.

If you console.log that particular test you will see a subtle difference in how that track was stored on the object.

Good luck.

Figures I’d miss that little detail. Thanks for the help and pointing me in the right direction.
