Tell us what’s happening:
Describe your issue in detail here.

Please do not mind my code. I know that he is not working well because i still lack some basic skills about it.
I was wondering one thing about this problem.

How do I “recognize” the different input that are stated in the function updateRecords ?

I can’t find how and what “records” purpose have. Which information is he gathering on this specific matter ? What is his anchor point ?
Also value, how can i know which part of the function is he working on ?

It’s a complete nightmare but i am starting to see the light, still, if someone can help me, i am pretty sure other people are still wondering on how this is all working.

Also, if i could add something, on the second task to accomplish, we have to target the ‘tracks’ value, but have to go through records[id].hasOwnProperty(“tracks”), how do i know that it’s the right path ?

Thanks in advance,

  **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 !== "") {
  return prop = value;
} else if (prop == "tracks" && "tracks" != undefined) {
  var array = [];
  var add = array.push(value);
} else if (prop == 'tracks' && value != "") {
  array.push(value);
} else if (value == "") {
  delete recordCollection.prop;
}
return records;
}

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

If you scroll down, at the bottom there is an example of how someone might call the function.

So 4 values are given to the function.

One recordCollection object, one number, a string and another string.

Hope this helps.
