Basic JavaScript - Record Collection

JavaScript
1

I don’t know what is missing, I can’t pass this check :

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

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

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