Tell us what’s happening:
Hi guys, don’t usually post on here but I’ve run into a serious block on this question for some reason. It feels weird because I’ve done harder algorithms on loops, etc. but else/if always seems to get me…
I tried to free wheel some code to get something down, but I feel I’m not really getting close to the solution.
Any help before I start reverse engineering from the solution would be very helpful. Oh and apologies for the terrible code! haha
Many thanks!
Your code so far
// Setup
var collection = {
2548: {

},
5439: {
album: "ABBA Gold"
}
};
// Only change code below this line
//collection[id][prop]
function updateRecords(id, prop, value) {
if (value = ""){
delete collection[id][prop];
} else if (prop !== "tracks" && value !== null){
collection[id][prop] = value;
} if (prop === "tracks"){
if (collection[id][tracks] === null){
tracks.push(collection[id]);
} else {
tracks.push(collection[id]);
}
}
return collection;
}
updateRecords(5439, "artist", "ABBA");
