Tell me whats wrong with the code pls

Tell us what’s happening:
It says After updateRecords(2468, “tracks”, “Free”), tracks should have “1999” as the first element.
Please help
Your code so far


// 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(prop != 'tracks' && value !=""){
    collection[id][prop] = value;
  }
    if(prop == 'tracks' && collection.hasOwnProperty('tracks') == false){
      collection[id]['tracks'] = [];
    }
    if(prop == 'tracks' && value !=""){
      collection[id]['tracks'].push(value);
    }
    if(value == ''){
      delete collection[id][prop];
    }
  
  return collection;
}

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

  if(prop == 'tracks' && collection.hasOwnProperty('tracks') == false){
      collection[id]['tracks'] = [];
    }

This will always be true because collection doesn’t have a tracks property.

Umm… can u explain further. Please

Look at the object collection.

Does it have a property named tracks?
