Summary
In this chapter, you learned about the performance tools provided by React and how to use them. We used the PERF add-on: shouldComponentUpdate and PureRenderMixin. We also saw which areas to look for when trying to improve the performance of our apps. We also studied the pitfalls while improving the performance, especially with PureRenderMixin. In the end, we discussed the importance and advantages of immutable data.
In the next chapter, we will look at the data model of React in detail using React Router and Flux. You will learn how to use React with other frameworks such as Backbone.
