Basic JavaScript - Record Collection

JavaScript

Tell us what’s happening:
Hello all, I am having trouble connecting the function parameters in this challenge and how they correlate to the objects in “recordCollection”
I went through the tutorials again (how to access objects with variables, how to update etc) and understand what happens in the tutorials, however in this challenge, I am finding it hard to see the logic or the connections.
How can we access the parameters(records, id, props, value) when they are not defined in “recordColletion”?

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) {
  return records;
}

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

The value of the function parameters are given by the arguments when the function is called. That way you don’t have to make a separate function for every possible records object
