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.

THIS TRAINING COURSE WILL HELP YOU:

  • Deepen modern Web APIs skills (WebSockets, Geolocation, BigInt)
  • Use JavaScript OOP: prototypes, ES6 classes, closures, getters/setters
  • Design modular code with import/export and manage npm dependencies
  • Use RegExp for validation and handle client storage (cookies, localStorage)
  • Build Node.js servers, use file system and apply security measures

WHO SHOULD ATTEND?

  • Developers with intermediate JavaScript aiming for advanced level
  • Frontend devs who want to add server-side Node.js skills
  • Programmers aiming for clean, modular and secure JavaScript code
  • Developers who need input validation and client-side storage skills
  • Those wanting to use tools like Babel, Webpack and npm
