  else if(prop=="tracks" && value.length !==0){;}

  else if(value.length==0){


  return records;


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 (’).

To start, you can’t access the properties with dot notation. id and prop are variables that hold the names of the properties that you want.

thank you this is my first time posting in the forum i will keep that in mind for the next time

This is where you really start learning three difference between “dot notation” (like and bracket notation (like library[isbn], where isbn might contagion a unique id string for a book).

thank you that was my mistake !
