In this chapter, we are going to stay connected around the use of React components and containers in our application. We will continue the code base we had in Chapter 1, Understanding Redux, through to Chapter 4, Concept of Immutability, in order to build user interfaces for our small hospital management system. While building the interfaces, we are going to learn about the principles of React, ReactJS life cycle components, accessing document object model (DOM) elements, and presentational and container components.

In this chapter, we are going to learn about the following topics:

• Components of React
• Principles of React
• New features in React 16
• Building user interfaces
• Building the project structure
