In this chapter, we started with understanding the React addons and how to use them. We used immutability helpers and test utility functions provided by the addons. We also looked into how to clone the components.

In the next chapter, we will make our React app more performant. You will be learning about addons that will improve the performance of the React apps. Specifically, you will learn how to measure the performance of our apps and how React can make faster updates without changing most of the UI.

Let's make our React apps faster!
