JavaScript (Node.js) for Beginners: Complete Course

This book is your ideal start into the world of JavaScript and server-side development with Node.js. It is created specifically for those who have never programmed or are just starting their journey in IT. You are holding a complete course that will guide you from installing a code editor to creating full-fledged server applications.

Unlike many textbooks, there is no dry theory here. Each chapter contains practical examples that you can immediately run on your computer. You will learn not just to write code, but to understand how it works "under the hood."

What you will learn from the book:

• JavaScript Basics: variables, data types, functions, objects, and arrays — all from scratch with clear examples.
• Flow Control: conditions, loops, error handling, and asynchrony (callbacks, promises, async/await).
• Node.js for Beginners: environment setup, module system, working with the file system and streams.
• Creating a Web Server: from a simple HTTP server to routing and request handling.
• Working with Databases: connecting to MongoDB and SQLite, executing queries, and saving data.
• Modern Tools: npm, package.json, dotenv, nodemon, and other useful packages.
• Final Project: creating a full-fledged REST API for notes with authorization and data storage.

Who this book is for:

• Absolute beginners who have never written code.
• Web designers looking to master the server side.
• Students of technical specialties.
• Anyone who wants to quickly enter IT and start earning from development.

The book is written in simple and accessible language. The author — a practicing developer with 10 years of experience — breaks down each topic step by step. You will not encounter complex terms without explanation. All examples can be downloaded from GitHub and run locally.

After reading, you will be able to independently create server applications, work with APIs, connect databases, and deploy projects on hosting. This is not just a textbook — it is your personal mentor in the world of JavaScript.

Start your journey into programming today. JavaScript is one of the most in-demand languages, and Node.js opens doors to backend development, automation, and even the world of IoT. Take the first step with this book!
