Node.js has become a go-to technology for building scalable and efficient server-side applications. Its event-driven, non-blocking I/O model makes it an excellent choice for handling real-time data-intensive operations and building high-performance network applications.

In this article, we’ll dive into the fundamentals of Node.js and explore its core features through practical examples.

Understanding Node.js

Node.js is an open-source, cross-platform runtime environment that executes JavaScript code outside of a web browser. It is built on top of the V8 JavaScript engine, the same engine used by Google Chrome.

Node.js allows developers to write server-side applications in JavaScript, which was traditionally used only for client-side scripting.

One of the key advantages of Node.js is its non-blocking, event-driven architecture. Unlike traditional server models that create separate threads for each incoming request, Node.js uses a single thread and an event loop to handle multiple concurrent connections.
