Tell us what’s happening:
Can’t solve this one
also is there an alternative for the NOT operator ?
In jQuery I could use .not
the
prop != track
just doesn’t seem right to me
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 != ""){
return prop = value;
}else if (prop in tracks || tracks != album){
return "" += value;
} else if (prop in tracks || value != ""){
return value.pop.tracks
}else (value = """) {
return delete prop
}
return object;
}
updateRecords(collection, 5439, 'artist', 'ABBA');
