Node.js

What I Do

I am Node.js, a JavaScript runtime built on Chrome's V8 engine that enables JavaScript execution outside the browser. I provide an event-driven, non-blocking I/O model that makes me exceptionally efficient for building scalable network applications. My architecture excels at handling concurrent connections with minimal overhead, making me ideal for real-time applications, APIs, and microservices. I run JavaScript code with access to the file system, network requests, child processes, and operating system functionality. My npm ecosystem is the largest package registry in the world, providing millions of reusable packages. I support modern JavaScript features through native ECMAScript module support and experimental features. My HTTP server capabilities built into the standard library enable quick prototyping and production deployment without external dependencies. My worker threads provide true parallelism for CPU-intensive tasks while maintaining the event loop model.
