Please what’s wrong with my code?
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" && value !== " ") {
  object[id][prop] = value;
}
else if (prop === "tracks" && object[id].hasOwnProperty("tracks") === false) {
  object[id][tracks] = value;
}
else if (prop === "tracks" && value !== "") {
  object[id][tracks].push(value);
}
else if (value === "") {
  delete object[id][prop];
}
return object;
}

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

Change

if (prop !== "tracks" && value !== " ") {
  object[id][prop] = value;
}

The value !== " " should be value !== ""

Next change

  object[id][tracks] = value;

to

  object[id]["tracks"] = [value];

The “tracks” property needs to be created as an array. Also tracks is not a variable so we use a literal string.

Lets try testing this condition first:

else if (value === "") {
  delete object[id][prop];
}

Another option is to rework your logic.

The line below also has to be changed:

else if (prop === "tracks" && value !== "") {
  object[id][tracks].push(value);
}

The [tracks] should be ["tracks"]

Just a few simple mistakes. Happens all the time. Placing console.log() throughout the program as you make it allows you to catch errors early on.
