Summary

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...
