Well yesterday I took an example (simple) react app and started adding in Redux to handle application state. I was following the examples in the book (Pro React 16) and it went pretty well. There is a lot of boilerplate code though. It's interesting that redux recommends using the redux toolkit which helps eliminate a lot of the boiler plate code. Again I find myself at a crossroads. Learn the old way first and then go to the latest recommendations or just plow ahead and do it using the latest recommendations. I think I'll complete the app as done in the book and then see how it differs and convert using toolkit if necessary.
