002 What you should know before watching this course

A new JavaScript library has arrived: React. js. React. js is designed to make the process of building modular, reusable user interface components simple and intuitive. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. In this course, Eve Porcello helps you get started with React. js, guiding you through the interface design of a sample bulletin board app. She reviews components, properties, and component state, as well as the foundational parent/child relationships within React. js. Eve also describes the lifecycle of components and how developers can trigger creation, lifetime, and teardown events. The course wraps with a chapter dedicated to building a more complete app with React. js and companion tools like Babel, NPM, and more.
