“ Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web pages. ”
“ Node.js is built on Chrome's V8 JavaScript engine, which provides high performance and scalability. Node.js is also event-driven, which means it can handle concurrent requests without blocking. This makes Node.js ideal for real-time applications such as chat and streaming. ”
