Advanced JavaScript and Introduction to Node.js (JVS2)

Programming, JavaScript

In this course you deepen core JavaScript skills and learn modern techniques such as Web APIs, BigInt and internationalization. You will explore OOP in JavaScript: prototypes, inheritance, ES6 classes, closures, getters and setters, and prototype extensions.

Next you move to server-side JavaScript with Node.js, covering file system access, modules, npm packaging and building a basic HTTP server for GET and POST. You will learn regular expressions, client storage (cookies, localStorage) and web security, plus Babel and Webpack.
