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 to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

@ashley5233

object[id][prop].hasOwnProperty === flase

Here, you aren’t using the hasOwnProperty method correctly. I’d Google the documentation to check how that method works.

Also, you probably want to check that the value is not an empty string in that conditional.

@ashley5233

    let tracks = []
    object[id][prop] = value

I don’t think this does what you think. You want the end result of this if clause to be that object[id]["tracks"] is an array with a single value.
