You'll also develop a responsive Event Registration form with powerful form validation which allows users to register for your upcoming event and use charts and graphics to display registration data. WebRTC enables real-time communication in a web browser. You'll learn how to use that as well, when you build a real-time video-call and chat application later in the book. Towards the end of the book, you will meet React, Facebook's JavaScript library for building user interfaces. You'll simply throw together a blog with React, and get the sense of why this kind of JavaScript framework is used for building large scale applications. To make your blog more maintainable and scalable, you'll be using Redux to manage data across the React components.
