Tell us what’s happening:
Help, I don’t know why the test for:
After updateRecords(5439, "tracks", "Take a Chance on Me")
, tracks
should have "Take a Chance on Me"
as the last element.
won’t pass, even though 4th one did.
Your code so far
// 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;
} else if (prop === "tracks" && collection[id][prop] === undefined) {
collection[id][prop] = [];
} else if (prop === "tracks" && value !== "") {
collection[id][prop].push(value);
} else {
delete collection[id][prop];
}
return collection;
}
// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
