Overview

With the massive improvements to function components in React via hooks and suspense, you may be interested in seeing how to refactor a typical class component to a simpler function component that uses React Hooks features. In this course, Kent will take a modern React codebase that uses classes and refactor the entire thing to use function components as much as possible. We’ll look at state, side effects, async code, caching, and more!
