Basic JavaScript - Record Collection

I feel like everything in the code is fine, but I have 5 out of 7

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 (value === "") {
    delete records[id][prop];
  }
  else if (prop !== "tracks" && value !== "") {
    records[id][prop] = value;
  }
  else if (prop === "tracks" && value !== "") {
     if (!records.hasOwnProperty("tracks")) {
    records[id].tracks = [];
  }
  records[id].tracks.push (value);
  }
  return records;
}

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

The records object will never have the property "tracks". Only individual record objects can have this property.

Got it, it is finally okay
Thank you.
