Hello, i’ve got a minor error?
Your code so far

// Setup
const recordCollection = {
  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(records, id, prop, value) {
 if (prop !== 'tracks' && value !== '') {
  object[id][prop] = value;
 } else if (prop === 'track' && object[id].hasOwnProperty) {
   object[id][prop] = value;
 } else if (prop === 'tracks' && value !== '') {
  object[id][prop].push(value);
} else if (value === '') {
  delete object[id][prop];
}
 return object;
}

updateRecords(recordCollection, 5439, 'artist', 'ABBA');

So, even before going into everything there is a big issue. When I post your code into the challenge I get the error ReferenceError: object is not defined. This is obviously because object is not defined. Why do you think it is saying that object is not defined?

I get it. my code is still failing unfortunally with " After

updateRecords(recordCollection, 5439, "tracks", "Take a Chance on Me") , tracks should have the string Take a Chance on Me as the last and only element."

 function updateRecords(object, id, prop, value) {
  if (prop !== 'tracks' && value !== '') {
  object[id][prop] = value;
 } else if (prop === 'track' && object[id].hasOwnProperty) {
   object[id][prop] = value;
 } else if (prop === 'tracks' && value !== '') {
  object[id][prop].push(value);
} else if (value === '') {
  delete object[id][prop];
}
 return object;
}


updateRecords(recordCollection, 5439, 'artist', 'ABBA');

Why are you calling this object? That is a bad name.

This is not how you call this method

This doesn’t create an array.
