Course Description

React (a.k.a. ReactJS or React.js) is a JavaScript library for developing user interfaces. This hands-on course introduces students to the React JavaScript library and covers essentials such as using Create React App, defining components, writing and styling JSX elements, passing props, using state and registering event handlers. Students will also learn how to use React Hooks, the Context API, Lifecycle Methods and how to implement global state using the Redux JavaScript library.

Comprehensive hands on exercises are integrated throughout to reinforce learning and develop real competency.
