revalidatePath allows you to purge cached data on-demand for a specific path.

I don't really get this, what is usually in cached data?

It’s useful for updating the page(s) where content has changed while still having it cached otherwise. It’s essentially on demand revalidation. It will cause fetching to be triggered again in those routes
