Node.js is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It is built on the V8 JavaScript engine, the same engine used by Google Chrome to execute JavaScript code. Node.js is designed for server-side scripting, making it an ideal choice for building scalable, real-time web applications. One of its key features is its asynchronous and non-blocking I/O model, which enables efficient handling of multiple concurrent connections, making it well-suited for applications that require high concurrency and responsiveness.
Node.js utilizes an event-driven architecture, operating on a single-threaded event loop, which allows it to handle numerous simultaneous connections without the need for spawning multiple threads for each connection. This characteristic ensures high efficiency and performance for real-time applications.
