Basic JavaScript: Record Collection (stuck)

Good evening All,

I just got stuck with this, could someone please check my code?

Thanks a lot.

Tell us what’s happening:

Your code so far


// Setup
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 !== "") {
collection[id][prop] = value;
}

if(prop === "tracks" && !collection[id].hasOwnProperty("tracks")) {
collection[id].tracks = [];
}

if(prop === "tracks" && value !== "") {
 collection[id].tracks.push(value);
}

if(value === "") {
delete collection[id][prop];
}

return collection;
}

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