Summary

In this chapter, you learned about Context. With Context, you can handle state for any React application. In combination with reducer functions, you can use it for building information architecture for your React application. State in React involves unidirectional data flow, synchronous update rounds, and predictable state transformations.

Next, we walked through a detailed implementation of a React application that uses Context. Context provides an implementation for complex state situations, the benefit of which is predictability everywhere.

Then, you learned whether Context has what it takes to build scalable architectures for our React applications. The answer is yes, for the most part. For the remainder of this book, however, we're going to explore GraphQL to see whether these technologies can scale your applications to the next level. In the next chapter, you'll learn about the concepts of GraphQL and what it means for a React application.
