Chapter 16. Component Composition
In this chapter, you will use component composition to build a reusable alert component. Component composition allows you to pass child components as props to another component, giving you flexible control over what renders. Component composition is a dynamic, powerful React tool that developers frequently use in component libraries.
You will use the alert component to display messages in two scenarios:
When the order submission is successful, you will display a thank-you message.
When the order submission fails, you will display an error message.
