Record Collection... Working, but am I doing it wrong?

JavaScript
1

Morning all.

My code works fine but is somewhat different from the solution given in the get a hint section. Is there anything wrong with my approach or should I stop worrying about it and go for a walk?

Thanks


// Setup

var collection = {
    "2548": {
      "album": "Slippery When Wet",
      "artist": "Bon Jovi",
      "tracks": [ 
        "Let It Rock", 
        "You Give Love a Bad Name" 
      ]
    },
    "2468": {
      "album": "1999",
      "artist": "Prince",
      "tracks": [ 
        "1999", 
        "Little Red Corvette" 
      ]
    },
    "1245": {
      "artist": "Robert Palmer",
      "tracks": [ ]
    },
    "5439": {
      "album": "ABBA Gold"
    }
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) {
if(!value){
    delete collection[id][prop];
  } else {
    if(prop === 'tracks'){
      if(!collection[id].tracks){
        collection[id].tracks = [];
      }
      collection[id].tracks.push(value);
    } else {
      collection[id][prop] = value;
    }
  }
  return collection;
}

// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
