Describe your issue in detail here.
Whats the issue in this I have trying for the fifth day straight though I cant pass this step.

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: [ 'tracks ', ‘Take a Chance on Me’ ]
},
5439: {
albumTitle: ‘ABBA Gold’,
tracks:
}
};

// Only change code below this line
function updateRecords(records, id, prop, value) {
if (!value){
delete records[id][prop]
} else if (prop != ‘tracks’) {
records[id][prop] =value
} else {
if (!records[id].hasOwnProperty(‘tracks’))
records[id].tracks =
}

return records;
}

console.log(updateRecords(recordCollection, 5439, ‘album title’));

// 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: [   'tracks   ', 'Take a Chance on Me' ]
  },
  5439: {
    albumTitle: 'ABBA Gold',
    tracks: []
     }
};
  
// Only change code below this line
function updateRecords(records, id, prop, value) {
  if (!value){
    delete records[id][prop]
  } else if (prop != 'tracks') {
    records[id][prop] =value
  } else {
    if (!records[id].hasOwnProperty('tracks')) 
      records[id].tracks = []
  }
 
return records;
}

console.log(updateRecords(recordCollection, 5439, 'album title'));

after this
records[id].tracks = [];
add

 records[id].tracks.push(value);

push the value to the existing ‘tracks’ array.
