Node.js

Node.js is a V8-powered JavaScript runtime (open-source, cross-platform) for building fast, scalable network applications and server-side logic.

Node.js runs JavaScript outside the browser, leveraging Google's high-performance V8 engine. Its core strength is the event-driven, non-blocking I/O model (asynchronous operations), which makes it ideal for building highly scalable, real-time applications: think chat services or high-throughput APIs. The platform is backed by npm (Node Package Manager), the world's largest software registry, offering developers over 2.5 million packages for rapid development and deployment. We use it for everything from microservices to command-line tools, ensuring efficient resource utilization.
