Basic JavaScript - Record Collection

Hi! I’ve managed to complete all the steps, except for the last one:
If the album doesn’t have a "tracks" property, create a new array for the album’s “tracks"property before adding thevalue` to it.”

From what I understand I have to assign a new array called tracks, but how do i name the array? I tried googling it, but couldnt really find anything.
Am I misunderstanding something?

my code:
function updateRecords(records, id, prop, value) {
if (value === “”) {
delete records[id][prop];
} else if (prop !== “tracks” && value !== “”) {
records[id][prop] = value;
} else if (prop === “tracks” && value !== “”) {
} else if (records[id].hasOwnProperty(“tracks”)) {
records[id] = newArray(“tracks”);
return records;
