Basic JavaScript - Record Collection

JavaScript
1

Hi world , sorry for asking for your help again , i got stuck again , i rewrited this code so many times and this is the closest i could get . One test is not checked and i cant figure it out what i did wrong

  **Your code so far**

// Setup
const 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 !== "") {
  records[id][prop] = value ;
}else if (prop === "tracks" && records[id].hasOwnProperty("tracks" === false)) {
  records[id][prop] = [value];
}else if (prop === "tracks" && value !== "") {
  records[id][prop].push(value);
}else if (value === "") {
  delete records[id][prop];
}
return records;
}

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

To find that error yourself you should check the way the input that doesn’t pass the test goes through your function .

Spoiler

I’m pretty sure that this line has a little error that might be the one that breaks your code
