React Router Prework

Router Overview

React Router is a library that allows us to make our single page React applications mimic the behavior of multipage apps.

SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
