I don't understand what does it do. A "website" for what? A user system? It makes a website for me in which users can sign up and login, but then what?
It's a starter/boilerplate.
When I move between the pages its noticeably slow, almost like you're actually loading a new page. I thought React was supposed to be fast?
Yes. It's more like a few single page apps. The account and admin areas feel much faster.
