what is wrong with my solution in the second else if why it is wrong if surely asks to update the tracks property and I put it directly using dot notation so why it is not working I even tried bracket notation and it also did not work why do I have to put the prop itself
// 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")) {
records[id].tracks = value
} else if (prop == "tracks" && value != "") {
records[id][prop].push(value)
} else if (value == "") {
delete records[id][prop]
}
return records;
}
updateRecords(recordCollection, 5439, 'artist', 'ABBA');
