Did you try it? Copy that line and run it.

</div>

yes, but you delete using `prop` so it is not necessary to check if `prop` is `"tracks"` or not  
you just delete when value is an empty string

True but I kept trying different things until it worked. I can make the code more concise but for now I want to pass this challenge and where I’m stuck is the tracks array can you explain how I can fix that?

In order to fix it, you have to _understand_ it.

Can you explain, in words, what you are trying to do here? I think that you are close, but your tests in the `if` are not quite right.

OK I will try. The problem seems to be that when the original collection does not have a tracks array I can’t assign the value to the prop.  
so in words if the property is tracks and there is an existing array push the item to the end.  
If there isn’t a array assign the the value as a string .  
I can take tat out and i will still get the same error message.

Ok, so you have the right idea, but your execution is wrong.

Above you were playing around with `hasOwnProperty` to see if a property is defined. Why did you go away from that?

Jeremy,  
I am new at Javascript and very new on the forum. I’m learning to navigate it as I use it. So I will make mistakes. ):

Sure, you will make mistakes. Everyone makes mistakes. I’m trying to help you fix the mistakes in your code.

So…

Please, work with me here. Why did you go away from `hasOwnProperty`? That’s a better approach than comparing against `=== []`, but I want to help you get `hasOwnProperty` working correctly.

Thank you for helping me with the code and with navigating the forum. I really appreciate it. I’m going to redo it with hasOwnProperty and show you.

ok I changed the last if else statements to

```auto
 if ( prop === "tracks" && records[id][prop].hasOwnProperty(prop) )
 {records[id][prop]= [value];}

 else

{records[id][prop].push(value);}

  return records;

```

And i still get the same error message.

ok, now let’s take a look at what you are doing here  
what is `records[id][prop]`? is that the object that can have the `tracks` property?

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`) to add backticks around text.

See [this post](https://forum.freecodecamp.org/t/forum-code-formatting/25574) to find the backtick on your keyboard.  
**Note:** Backticks (`) are not single quotes (').

Jeremy thank you for your help! It finally passed. My mistake was that when I was typing records[id][prop].hasOwnProperty and I should not have included [prop] since that is what I was checking just records[id].hasownproperty(prop) . Is this the correct explanation?? Anyway thank you very much it finally passed!

Bingo. You want to know if `records[id]` has the property, not if `records[id][prop]` has the property.
