Node.js

Node.js is a server-side JavaScript runtime environment designed for building fast, scalable, and event-driven applications. It allows developers to use JavaScript for both frontend and backend development, streamlining the application architecture.

Built on Google’s high-performance Chrome V8 engine, Node.js executes JavaScript code outside the browser, enabling server-side operations. It utilises non-blocking I/O and asynchronous programming models, which are ideal for applications that require real-time interaction, such as messaging services, APIs, and Internet of Things (IoT) platforms.

Node.js supports an extensive ecosystem of libraries and modules via npm (Node Package Manager), facilitating rapid development and integration. Its lightweight architecture, combined with high concurrency handling, makes it a preferred choice for modern web services and microservice-based architectures.
