Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to build fast and scalable server-side applications. Unlike traditional JavaScript, which runs in the browser, Node.js runs on the server, enabling backend development using JavaScript. It uses an event-driven, non-blocking I/O model, making it efficient for handling multiple requests simultaneously, which is ideal for real-time applications like chat apps, APIs, and streaming services.

Getting started with the Node.js Tutorial is simple. Begin by installing Node.js from the official website, which also includes npm (Node Package Manager) for managing packages and libraries. You can create a basic server using just a few lines of code and handle HTTP requests efficiently. Node.js also integrates seamlessly with popular frameworks like Express.js, making web development faster and more organized.

By learning Node.js, developers gain the ability to write both frontend and backend code in JavaScript, streamlining development and improving productivity. It’s highly popular among startups and large-scale applications due to its scalability and performance.
