Basic JavaScript - Record Collection

Hello,

I’ve encountered a problem with my work. I get an reference error; tracks not defined. Can anybody help me with this, I’ve been stuck for a while and don’t know what to do.

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[id].hasOwnProperty("tracks") === false) {
      records[id][prop] = [];
    }
    records[id][prop].push(value)
  }

  return records;
}

console.log(updateRecords(recordCollection, 5439, 'artist', 'ABBA'));

Here’s you treated ‘tracks’ like a variable instead of a string, but there is no such variable
