What is Node.js?
Node.js is event-driven, meaning that it uses an event loop to handle incoming requests and processes them asynchronously. This allows Node.js applications to handle large volumes of requests while maintaining high performance and scalability. Node.js also includes a rich set of built-in modules that provide functionality for file system access, networking, cryptography, and more.
