Help with this JS coding task

Hi! Can anyone help me out a bit in understanding what this question is even asking me to do? Thank you! I feel totally stumped for some reason.

Your code so far

// Setup
var collection = {
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(object, id, prop, value) {
return object;

updateRecords(collection, 5439, 'artist', 'ABBA');

Challenge: Record Collection

Link to the challenge:

I think you should start by explaining what specifically you don’t understand. The requirements are broken into five points. The first point is already done for you in the default code, so you have four left to go. I think you should just work your way through the remaining points one at a time and implement them in the function. Don’t worry about trying to get tricky with your code, just brute force your way through each point. And if you don’t understand something specific about a point then you can ask that specific question here.
