JavaScript with Node JS (A Complete Guide to JavaScript, ES6+, Node.js, NPM, Express.js, REST APIs, MongoDB, Authentication, and Real-World Backend Projects)

JavaScript with Node JS is a practical and comprehensive guide designed to help beginners and students learn JavaScript and use it to build modern backend and web applications with Node.js.

The book starts with JavaScript fundamentals and progresses to modern ES6+ features, asynchronous programming, modules, APIs, and server-side JavaScript. Readers will then learn Node.js, its event-driven architecture, NPM, built-in modules, HTTP servers, file handling, and asynchronous programming.

The book also covers Express.js, REST API development, MongoDB, Mongoose, authentication, JWT, security, and database integration, providing the foundation required to develop real-world backend applications.

With practical examples, exercises, and projects, this book helps readers understand how JavaScript can be used beyond frontend development to create scalable server-side applications and complete web solutions.
