So you’ve decided to build a React app. It has a few screens, so you need a router. And react-router seems pretty popular, so you
npm install it and put together a quick demo. Everything seems fine and dandy!
Or it did, until you googled for some docs the next day. Something seems off. The logo has changed colour from blue to red. And the version number has mysteriously increased from 2 to 4. Huh?
