The docs are super good. I love the "embedded browser" that shows how it works.
Shameless self plug: our book [1] has a whole chapter on Routing in React with this new v4 router. After you've finished reading the docs, if you want a tutorial style walk-through of this router v4, we build a Spotify-type clone over the course of 75+ pages.
Over the last month (or so), I've been reading and reviewing React books on my blog [1]. I liked Fullstack React, but there is one big thing that keeps me from recommending it: most of the examples still use the createClass from ES5. For learning React in 2017, I (just my opinion) expect the book to fully embrace ES6/7 in all the examples.
I am considering buying this for an engineer that works for me to get up to speed on React in the very near future. I only want to start him on ES6+ syntax though. How long do you think until it will be up-to-date?
The first chapter has already been updated to use ES6 class syntax, and we explain how it works there. We're converting the rest of the book to use ES6 classes (and removing createClass) over the next week or two.
