Hi @Yusuf2 !

Welcome to the forum!

Where did you define obj?

You probably meant to use the function parameter instead.

I defined it at number 23 typing that obj.hasOwnProperty(name).

That’s not how you define it. :grinning:
That is what the computer is telling you.

It has no clue what obj is.

Besides, you are not using the function parameter.
That is what you need to use instead.

How do i use it please.

This is the function parameter

But you are not using it at all.

Instead of using obj which is not defined you need to use the function parameter.

make sense?

What is updated code.

Can you write in the forum what you tried using the function parameter?

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 (’).

So what should i use it to do.

You mentioned that you tried using the function parameter but it didn’t work, right?

I want to see your new code so I can help you pass the test.

So I should reset the code.

I’ll try to explain the problem in a different way and maybe that will help you solve it.

You need to replace the word obj here

with the function parameter (userObj)


Then the test will pass.

I am not allowed to give you full answers on the forum but hopefully that was a big enough clue on how to pass the test.
