I have done all the steps except one. I am unable to find where I am wrong ?

Your code so far

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'
  }
};

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

console.log(updateRecords(recordCollection, 5439, "artist", "ABBA"))

This is the 5th user story

  1. If prop is tracks and value isn’t an empty string, add value to the end of the album’s existing tracks array.

Collection initially:

{ '1245': { artist: 'Robert Palmer', tracks: [] },
  '2468': 
   { albumTitle: '1999',
     artist: 'Prince',
     tracks: [ '1999', 'Little Red Corvette' ] },
  '2548': 
   { albumTitle: 'Slippery When Wet',
     artist: 'Bon Jovi',
     tracks: [ 'Let It Rock', 'You Give Love a Bad Name' ] },
  '5439': { albumTitle: 'ABBA Gold' } }

Collection after updateRecords(recordCollection, 2468, "tracks", "Free"), with code above:

{ '1245': { artist: 'Robert Palmer', tracks: [] },
  '2468': { albumTitle: '1999', artist: 'Prince', tracks: [ 'Free' ] },
  '2548': 
   { albumTitle: 'Slippery When Wet',
     artist: 'Bon Jovi',
     tracks: [ 'Let It Rock', 'You Give Love a Bad Name' ] },
  '5439': { albumTitle: 'ABBA Gold' } }
