## Description

node-lessons is a comprehensive Node.js programming course and instructional guide. It provides a collection of guided lessons and code examples designed to teach the fundamentals of the Node.js runtime and server-side JavaScript development.

The project serves as a practical guide for building web servers and backend applications, specifically covering the implementation of HTTP servers, request routing, and middleware chains. It includes specialized instructional material on managing asynchronous JavaScript workflows through promises and flow control, as well as guides for integrating NoSQL databases with a focus on object mapping and horizontal scaling.

The course extends into quality assurance and data acquisition, providing a framework for unit testing, API validation, and headless browser testing with code coverage. It also covers web scraping techniques using CSS selectors and the management of user sessions through encrypted cookies.

The repository includes environment setup instructions for managing runtime versions and executing JavaScript interactively.
