I am stuck here, kindly help me

Your code so far


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


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

function updateRecords(object, id, prop, value) {
  if (prop === "tracks" && (!(collection[id]).tracks)) {
    collection[id].tracks = [];
  }
  if (prop === "tracks" && value !== "") {
    collection[id].tracks.push(value);
  } else if (prop !== "tracks" && value !== "") {
    collection[id][prop] = value;
  } else if (value === "") {
    delete collection[id][prop];
  }
return collection;
}

Yep, the logic is ok, but you are not using the first argument. If you were referencing some old solutions, be aware that the function signature changed for this challenge.
