JavaScript: Record Collection, bug?

I’ve created my own code, replicated 3-4 codes found by other users encountering the same situation… but in the end I’m not able to get past these 2 checks… and I’ve spent an hour just doing this… is this a bug?

// running tests
After updateRecords(collection, 2548, “artist”, “”) artist should not be set
After updateRecords(collection, 2548, “tracks”, “”) tracks should not be set
// tests completed

My code so far is:


// Setup
var collection = {
2548: {
  albumTitle: 'Slippery When Wet',
  artist: 'Bon Jovi',
  tracks: ['Let It Rock', 'You Give Love a Bad Name']
},
2468: {
  albumTitle: '1999',
  artist: 'Prince',
  tracks: ['1999', 'Little Red Corvette']
},
1245: {
  artist: 'Robert Palmer',
  tracks: []
},
5439: {
  albumTitle: 'ABBA Gold'
}
};

// Only change code below this line
function updateRecords(object, id, prop, value) {
var album = collection[id];
if (value === "") {
  delete album[prop];
}
else{
if (prop !== "tracks" && value !=="") {
  if (value !== "") {
    album[prop] = value;  
  }
} else {
  if (!album[prop] && value !=="") {
    album[prop] = [];
  }

  if (value !== "") {
    album[prop].push(value);
  } 
}
}
return collection;
}

Challenge: Record Collection

Link to the challenge:

the challenge was recently updated, so there is a small difference between anything you find around and current requirements: be sure to use the new object parameter in your function and not reference the global collection

Oh god, I got confused. I can now see the function taking in Object instead of Collection. Works like a charm now.
