Describe your issue in detail here.

Hi all! I’ve been working on the Record Collection but I’ve sort of hit a roadblock and I’m not really sure how to proceed. Does anyone know if I’m at least on the right track with my code and what any issues with the syntax/logic may be? Any advice is appreciated!

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

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

just a couple notes:

this part should be checking records, not updateRecords. second, because of how you have the equal sign, it’s not checking for equality, it’s setting records.value to ‘’

this part is creating a new array, but not assigning it to anything.

one more. here, tracks is not an initialized value. it won’t known that you’re wanting to push to records.id.tracks. Also, you’re using updateRecords instead of records, but really you just need to push value and nothing else
