React, Redux and TypeScript

• HTML basics
• experience with JavaScript

React is a widely-used library for creating single page applications in JavaScript and HTML. It is used by companies such as Facebook, Instagram, Netflix or the New York Times.

This course will introduce the foundations on which React and other libraries (like Angular and Vue.js) are based on and highlight the sepecifics of React. It will also cover technologies that are commonly used with React, like Redux and React-Router.

By the end of this course participants will be able to build applications of various complexity with React while adhering to best practices.
