Explanation of parentheses

[erquhart]

Hi all,

I'm trying to understand the role of parentheses in route names, eg., (app)/(auth). I see mention of route groups in the authentication guide, and I'm guessing these parentheses are related to that concept, but this syntax isn't explained head on and I'd like to understand it.

Is it just a pattern like the use prefix on hooks or are parens wrapped folders treated differently than others?

Found it in the docs: https://expo.github.io/router/docs/features/routing#groups
