Thanks for your honest feedback! I agree with your opinion. But at some point I had to make a decision how to address the ES6 topic. In the end my opinion was that you can't get away from learning ES6. Personally I learned ES6 on the way when I picked up React. It felt just natural and I hope that the readers will do so as well. Still I tried to cover most of the code pieces in an explicit way before I do them more implicit. But I have to be honest that I didn't thought about (<div>...</div>) vs { <div>...</div> } :)
