Chapter 1, Why React?, covers the basics of what React really is, and why you want to use it.
Chapter 2, Rendering with JSX, explains that JSX is the syntax used by React to render content. HTML is the most common output, but JSX can be used to render many things, such as native UI components.
Chapter 3, Component Properties, State, and Context, shows how properties are passed to components, how state re-renders components when it changes, and the role of context in components.
Chapter 4, Getting Started with Hooks, gets you moving with the new Hooks React API that replaces many legacy React APIs.
Chapter 5, Event Handling – The React Way, explains that events in React are specified in JSX. There are subtleties associated with how React processes events, and how your code should respond to them.
Chapter 6, Crafting Reusable Components, shows that components are often composed using smaller components. This means that you have to properly pass data and behavior to child components.
Chapter 7, The React Component Life Cycle, explains how React components are created and destroyed all the time. There are several other life cycle events that take place in between, where you do things such as fetch data from the network.
Chapter 8, Validating Component Properties, shows that React has a mechanism that allows you to validate the types of properties that are passed to components. This ensures that there are no unexpected values passed to your component.
Chapter 9, Handling Navigation with Routes, explains that navigation is an essential part of any web application. React handles routes declaratively using the react-router package.
Chapter 10, Code Splitting Using Lazy Components and Suspense, shows you how to structure your components so that only code that's needed is loaded into the browser.
Chapter 11, Server-Side React Components, discusses how React renders components to the DOM when rendered in the browser. It can also render components to strings, which is useful for rendering pages on the server and sending static content to the browser.
Chapter 12, User Interface Framework Components, introduces you to the popular Material-UI React framework for building responsive UIs.
