React got that name for a reason. It’s a component-based JavaScript library that renders smartly and can seriously simplify your work.

This course is for React newbies and anyone looking to build a solid foundation. It’s designed to teach you everything you need to start building web applications in React right away.

Each lesson in this 28-part course is a single index.html file. This keeps your focus on learning React, with no distractions. We’ll start with a blank file and add more complexity as we go along, wrapping the course with a lesson on how to move into a more production-ready development environment—and even deploy your app to a great service like Netlify.

You’ll build a solid understanding so when you come across JavaScript challenges down the road, you’ll know how to…react.

Thousands of people have used this course as an introduction to the core concepts of React. It's been reviewed and updated and is relevant and valid. There isn't a better introduction to React online.
