Confused about "last element" so close to finishing

Tell us what’s happening:
I got everything working except for making “take a chance on me” be the last element.

Your code so far


var collection = {
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(object, id, prop, value) {

if (prop !== 'tracks' && value !== ''){
object[id][prop] = value }

if (prop === 'tracks' && object[id].hasOwnProperty('tracks') === false){
 object[id][prop] = value;
}

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

updateRecords(collection, 5439, "artist", "ABBA")

If object doesn’t have tracks property, add the tracks as array with value in it…

Let me know, if this solved your problem, I’ll try to explain another way

so the issue was that tracks wasn’t an array!
