What information was incorrect, unhelpful, or incomplete?

Hi! Thanks for the all work on MDN.

On the page about \p and \P escapes for Unicode RegExp, as far as I can tell, there is no mention of the fact that \p means "match the category" and \P means "match the negated category"

What did you expect to see?

There should be a line explaining that one is the negation of the other.

Do you have any supporting links, references, or citations?

There's the following sentence:

\P creates a complement class that consists of code points without the specified property.

#38012 also added more information about what that means exactly.

Ah, I missed this sentence. IMHO this buried too deep and the distinction belongs in the abstract at the top.
