In this chapter, you learned about various tools from the React ecosystem—development, testing, and production tools that we have used in various stages of our app development. We discussed Babel, the JavaScript transpiler, to convert our next generation JavaScript code to ES5. We also saw how to use ESLint and React dev tools that make React development easy. In the end, we saw how Webpack can be used with React with its powerful loaders and configuration options. We saw how these tools can make developing React apps a beautiful experience.

In the next chapter, we are going to dive deep into Flux as an architecture. We have seen how problems arise during data sharing across components. We will see how to overcome them using Flux.
