I'm totally don't understand what to do here and for what reason

HI @ddrreeww !

Welcome to the forum!

I redacted your link to the screenshot because people are leary of clicking on unknown links.

It looks like you need help with a fcc challenge.

Please include the link for that challenge and write your code directly in the forum so we can help you.

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 (’).
