Collection solution

Getting no progress on solving,

Here are the requirements

You start with an updateRecords function that takes an object like collection , an id , a prop (like artist or tracks ), and a value . Complete the function using the rules below to modify the object passed to the function.

  • Your function must always return the entire object.
  • If prop isn’t tracks and value isn’t an empty string, update or set that album’s prop to value .
  • If prop is tracks but the album doesn’t have a tracks property, create an empty array and add value to it.
  • If prop is tracks and value isn’t an empty string, add value to the end of the album’s existing tracks array.
  • If value is an empty string, delete the given prop property from the album.

Note: A copy of the collection object is used for the tests.

Here is my solution with 0 successes… Help

// 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) {
  if (prop !== "tracks" && value !== "") {
    collection[id][prop] = value;
  } else if (prop === "tracks" && !condition[id].hasOwnValue("tracks")) {
    collection[id].album = [];
  } else if (prop === "tracks" && value !== "") {
    collection[id].tracks.push(value);
  } else if (value === ""){
    delete collection[id].album[prop];
  }
  
  return object;
}

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

Anything would be super helpful.
