Node.js

About

Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code on the server side. It is built on the V8 JavaScript engine, which compiles JavaScript into efficient machine code, enabling fast execution and high performance. Node.js operates on a single-threaded, event-driven architecture, utilizing an event loop to handle multiple concurrent operations without blocking. This non-blocking I/O model makes it ideal for building scalable, high-performance network applications. Node.js is widely used for server-side development, particularly in real-time applications, web servers, APIs, and microservices. Its asynchronous nature allows it to handle I/O-intensive tasks efficiently, making it suitable for data streaming and real-time data processing. Node.js supports various platforms, including Windows, Linux, and macOS, and is managed by the OpenJS Foundation. It offers a vast ecosystem of packages via npm, facilitating rapid development and deployment of applications.
