Hello,
I’ve encountered a problem with my work. I get an reference error; tracks not defined. Can anybody help me with this, I’ve been stuck for a while and don’t know what to do.
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 (value === "") {
delete records[id][prop];
}
else if (prop !== tracks && value !== "") {
records[id][prop] = value;
}
else if (prop === tracks && value !== "") {
if (records[id].hasOwnProperty("tracks") === false) {
records[id][prop] = [];
}
records[id][prop].push(value)
}
return records;
}
console.log(updateRecords(recordCollection, 5439, 'artist', 'ABBA'));
