Record collection I add new value to array, solution doesn't recognizes it

I am almost done with this challenge, except that when the test code is:
updateRecords(5439, “artist”, “ABBA”);
my solution reads:
“artist”: [“ABBA”]
which is not recognized as solved.
If I don’t add the artist:ABBA to an empty array, I pass this test, but not others.
which is not recognized as solved.
Any suggestions?

also I am not sure what is the proper way to show my solution so far

Please share your code and tell us what the failing test says.

// 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) {
  var object = collection[id];
     object[prop] = [];
  //  if (object[prop].length==1){
  //    object[prop] = object[prop].toString();
  //  }
      delete object[prop];
    return collection;

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

I don’t pass this test
After updateRecords(5439, “artist”, “ABBA”), artist should be “ABBA”
(I pass all other tests)

my solution shows:
‘5439’: { album: ‘ABBA Gold’, artist: [ ‘ABBA’ ] }

if I don’t put this value inside an array, I pass this test
(‘5439’: { album: ‘ABBA Gold’, artist: ‘ABBA’ }

I’ve edited your post for readability. When you enter a code block into the forum, precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.


artist should be a string, not an array.
"ABBA" is not the same thing as ["ABBA"]

yes, I see the difference. What was not clear to me was that only for tracks key I should create a new, empty array. So for the artist key, I will add the value as string.
Thank you for clarifying this. (and for your help with formatting)

I just did this change, and it works. thanks again
