Record Collection Addicted to Love

Tell us what’s happening:

I cant seem to figure out how to add the Addicted to Love part. I tried push command which didn t work out well :stuck_out_tongue: any hint?

  **Your code so far**

// Setup
const recordCollection = {
2548: {
  albumTitle: 'Slippery When Wet',
  artist: 'Bon Jovi',
  tracks: ['Let It Rock', 'You Give Love a Bad Name']
2468: {
  albumTitle: '1999',
  artist: 'Prince',
  tracks: ['1999', 'Little Red Corvette']
1245: {
  artist: 'Robert Palmer',
  tracks: []
5439: {
  albumTitle: 'ABBA Gold'

// Only change code below this line
function updateRecords(records, id, prop, value) {
if (prop !== 'tracks' && value !== "") {
  records[id][prop] = value;
} else if (prop === 'tracks' && records[id].hasOwnProperty("tracks") === false) {
records[id][prop] = [value];
} else if (value === "") {
  delete records[id][prop];
return records;
updateRecords(recordCollection, 5439, 'artist', 'ABBA');

Hi @Luciferian, welcome to the forum.

Let’s analyse what your if statement are covering:

  • else if (prop === 'tracks' && records[id].hasOwnProperty("tracks") === false)

This is checking that props is "tracks" and that at the same time "tracks" is not present for that object.

Which may be fine for an object like this:

5439: {
  albumTitle: 'ABBA Gold'

But what about

1245: {
  artist: 'Robert Palmer',
  tracks: []

This object has a “tracks” prop, so it won’t mach your previous if condition.
Which is exactly what is failing:

updateRecords(recordCollection, 1245, "tracks", "Addicted to Love")

Is attempting to add a track to that specific object, but you have no case covering that.

Hope this help :sparkles:
