**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(prop!=="tracks" && value!==""){
records[id][prop]=value;
}
else if(prop==="tracks"&& records[id].hasOwnProperty("tracks")===false){
records[id][prop]=[value];
}
if(prop==="track"&& value!==""){
records[id][prop].push(value);
}
if(value===""){
delete records[id][prop];
}
return records;
}
console.log (updateRecords(recordCollection, 5439, 'artist', 'ABBA'));
