In this book, you’ll learn how to create well structured and reusable react components that are easy to read and maintain by leveraging modern web development techniques. We will start with learning core TypeScript programming concepts before moving on to building reusable React components. You'll learn how to ensure all your components are type-safe by leveraging TypeScript's capabilities, including the latest on Project references, Tuples in rest parameters, and much more. You'll then be introduced to core features of React such as React Router, managing state with Redux and applying logic in lifecycle methods. Further on, you'll discover the latest features of React such as hooks and suspense which will enable you to create powerful function-based components. You'll get to grips with GraphQL web API using Apollo client to make your app more interactive. Finally, you'll learn how to write robust unit tests for React components using Jest.

In this chapter, we learned about container components and how they can be used to manage state and what presentational components need to do. Presentational components can then focus on what they need to look like. This allows presentational components to be more easily reused in multiple places and unit-tested.

We learned that compound components are components that rely on each other. Declaring compound children as static members on the parent class make it clear to a consumer that the components should be used together. React context is a convenient way for compound components to share their state.

We learned about the special children prop that can be used to access and render a component's children. We then learned that we can create our own render props to give consumers great flexibility for custom-rendering sections of a component.

In the last section, we...
