My code seems to work, but it isn’t passing the tests. See the screenshot for an example. My code does indeed add artist
of "ABBA"
, but there’s no green check mark next to that challenge.
// Setup
var collection = {
"2548": {
"album": "Slippery When Wet",
"artist": "Bon Jovi",
"tracks": [
"Let It Rock",
"You Give Love a Bad Name"
]
},
"2468": {
"album": "1999",
"artist": "Prince",
"tracks": [
"1999",
"Little Red Corvette"
]
},
"1245": {
"artist": "Robert Palmer",
"tracks": [ ]
},
"5439": {
"album": "ABBA Gold"
}
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));
// Only change code below this line
function updateRecords(id, prop, value) {
if(prop !== 'tracks' && value !== "") {
collection[id][prop] = value;
}
if(prop == 'tracks' && !collection[id].hasOwnProperty(prop)) {
var array = [];
collection[id][prop] = array;
}
if(prop == 'tracks' && value !== "") {
collection[id][prop].push(value);
}
if(value === "") {
delete collection[id][prop];
}
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
