React Training Overview

React is a JavaScript library for building web user interfaces and is one of the most wanted and loved web frameworks today. React makes it painless to create interactive UIs on top of web standards and is often used with the Redux library for managing the data or state in a React application.

In this React course, students gain hands-on experience with the latest version of React and the tools for developing React applications. Developers learn the skills they need to immediately build React and Redux applications using the TypeScript language.

Note: This React class can also be taught using JavaScript/ECMAScript.
