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.
