Book Description
Welcome to your big-picture guide to the React ecosystem.
If you're new to React and looking to become a professional React developer, this book is for you. This updated fifth edition reflects the current state of React, including React framework coverage as well as TypeScript.
Part 1 introduces you to React. You'll discover JSX syntax, hooks, functional components, and event handling, learn techniques to fetch data from a server, and tackle the tricky problem of state management. Once you're comfortable with writing React in JavaScript, you'll pick up TypeScript development in later chapters.
Part 2 transitions you into React Native for mobile development. React Native goes hand-in-hand with React. With your React knowledge behind you, you'll appreciate where and how React Native differs as you write shared components for Android and iOS apps. You'll learn how to build responsive layouts, use animations, and implement geolocation.
By the end of this book, you'll have a big-picture view of React and React Native and be able to build applications with both.What you will learnExplore React architecture, component properties, state, and context
