JavaScript (Node.js) for Beginners: Complete Course

This book is specifically designed for those who want to learn modern JavaScript from scratch and build server-side applications on the Node.js platform. You won't find dry theory here — only practical examples, clear explanations, and step-by-step instructions.

What is this book about?

The book covers the complete journey from the first installation of Node.js to developing a full-fledged web application. Starting with the basics of JavaScript syntax (variables, functions, objects, arrays), you will gradually move on to more complex topics:

• Asynchronous programming: callbacks, promises, async/await — learn to work with I/O operations without blocking the application.
• CommonJS module system: creating and importing your own modules, working with npm.
• Working with the file system: reading, writing, deleting files, working with streams.
• Creating a web server: from a simple HTTP server to handling routes and static files.
• Working with databases: connecting to MongoDB and SQLite, executing queries.
• Creating a REST API: designing endpoints, handling JSON, data validation.
• Advanced topics: working with the environment, debugging, testing, deploying the application.

Who is this book for?

• Beginners who have never programmed but want to start with JavaScript and Node.js.
• Web developers familiar with the frontend who want to master the server side.
• Students and self-taught learners looking for structured and understandable educational material.
• Anyone who wants to build fast and scalable server-side applications.

What will you learn and be able to do after reading:

• Confidently write code in JavaScript using modern ES6+ features.
• Understand how asynchrony works in Node.js and use it effectively.
• Create web servers and handle HTTP requests.
• Work with databases and build REST APIs.
• Develop full-fledged server-side applications ready for deployment.
• Use npm packages and manage project dependencies.

Each chapter contains practical tasks and code examples that you can immediately run and modify. The book is written in a lively, accessible language; complex concepts are explained using analogies and simple examples. This is not a reference guide, but a complete educational course that will take you from absolute zero to a confident Junior Node.js developer level.
