Hit the ground running with React, the open source technology from Facebook for building rich web applications fast. Updated for the latest React release, the second edition of this hands-on guide shows you how to build React components and organize them into maintainable large-scale apps. If you're familiar with JavaScript syntax, you're ready to get started.
