Record Collection- my own code

I do not know what is wrong with my code that did not run perfectly. Can anyone help me with that? I based on the hint code to do my own code but it does not seem to work

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

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

seems to work for me. just change last line to
a=updateRecords(5439, “artist”, “ABBA”);
console.log(a)
then press f12 in firefox to see the console output

I guess this is trivial

you’re missing a “s” in the 3rd line of your function i.e. “track” instead of “tracks”

function updateRecords(id, prop, value) {
  if (prop !== "tracks" && value !== "" )
  {collection[id][prop]= value; }
  else if (prop == "tracks" && collection[id].hasOwnProperty("track**s**") == false)
