I don’t understand why I’m failing this one. It keeps on saying
After updateRecords(collection, 2548, "artist", "")
, artist
should not be set.
After updateRecords(collection, 2548, "tracks", "")
, tracks
should not be set.
Even though I think that should be solved by the last (else if) already. Please help me.
// 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
var collectionCopy = JSON.parse(JSON.stringify(collection));
function updateRecords(collection,id, prop, value) {
if (prop !== "tracks" && value!== " "){
collection[id][prop] = value;
}
else if (prop === "tracks" && collection[id].hasOwnProperty([prop])){
collection[id][prop].push(value);
}
else if (prop === "tracks" && !collection[id].hasOwnProperty([prop])){
collection[id][prop]=[value];
}
else if (value === " "){
delete collection[id][prop];
}
return collection;
}
console.log(collection)
updateRecords(collection, 2548, "artist", "");
