Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, making it ideal for building scalable and high-performance network applications.
Node.js is built on the V8 JavaScript engine, which is developed by Google for the Chrome browser. This engine compiles JavaScript directly into native machine code, allowing Node.js to achieve high performance.
One of the key features of Node.js is its package management system, npm (Node Package Manager), which provides access to a vast ecosystem of libraries and tools that can be easily integrated into Node.js applications.
Node.js is commonly used for building web servers, API servers, real-time applications, and various types of backend services. It has gained significant popularity in the developer community due to its versatility, performance, and the rich ecosystem of libraries and frameworks available.
