Use them to split components into smaller functions manage state and side effects and access React features without classes all without having to rearrange your component hierarchy. React Hooks in action teaches you to write fast and reusable React components using Hooks. Youll start by learning to create component code with Hooks. Next youll implement a resource booking application that demonstrates managing local state application state and side effects like fetching data. Code sample and illustrations make learning Hooks easy
