Record Collection, it does not delete the prop?

This line of code is wrong?

else if (value === “”) {
delete records[id][prop];
}

Describe your issue in detail here.

  **Your code so far**

// Setup
var recordCollection = {
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(records, id, prop, value) { 
if (prop !== "tracks" && value !== undefined) {
  records[id][prop] = value;
} else if (prop === "tracks" && records[id][prop] === undefined) {
records[id][prop] = [value];
} else if (prop === "tracks" && value !== undefined) {
records[id][prop].push(value);
} else if (value === "") {
delete records[id][prop];
}
return records;
}

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