// Only change code below this line
function updateRecords(object, id, prop, value) {
 if(prop !== 'tracks' && value !== "") {

Hello there.

Do you have a question?

If so, please edit your post to include it in the Tell us what’s happening section.

The more information you give us, the more likely we are to be able to help.

Essentially you are asking why it isn’t working. If you leave comments in your code that can also help people more easily debug your thinking. It’s much better to catch a mistake in your thinking so as to prevent repeating that mistake in other exercises than to just help you correct the code.

Maybe break down the problem into steps using console.log and see where the outcome is unexpected.

you never use object parameter, instead you reference global object
