I am new to using nextjs, after doing the dashboard tutorial, the _app.js file is never used, I do not understand the difference with the layout.js file at the root of /app.
in which case to use a _app.js file? Thank you.

the
_app file is only used with the pages router, if you are using the app router it has no use. you can read more about it here: https://nextjs.org/docs/pages/building-your-application/routing/custom-app6 Replies

Also, if you're just starting out with Next.js focus on learning the new patterns that came along with the app router (Next.js v13 and above) and React 18 (so RSCs, Server Actions and co.)
