Beginning ReactJS Foundations Building User Interfaces with ReactJS

20Going Further

I've covered a lot of material in this book, but your React learning journey is just beginning. The React ecosystem is giant, active, and growing. What this means is that developers are constantly creating new tools to use with React and improving existing ones.

With all the activity, having a guide to the next steps can be invaluable. In this chapter, I'll give you a head start on where to go from here by discussing or expanding on some of the topics that I didn't have room for earlier in the book.
