Tell us what’s happening:
// When I run the test with this I pass the challenge
console.log(updateRecords(5439, "tracks", "Take a Chance on Me"));
// When I run with this I don't
console.log(updateRecords(5439, "artist", "ABBA"));
or
console.log(updateRecords(5439, "artist", ""));
Your code so far
// Setup
var collection = {
2548: {
album: "Slippery When Wet",

]
},
2468: {

"Little Red Corvette"
]
},
1245: {
artist: "Robert Palmer",
tracks: [ ]
},
5439: {
album: "ABBA Gold"
}
};
// 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].hasOwnProperty("tracks") == false) {
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
console.log(updateRecords(5439, "artist", ""));
