What is Node.js?

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It allows developers to execute JavaScript code server-side, enabling the creation of scalable network applications.

Asynchronous Programming

Node.js uses an event-driven, non-blocking I/O model, making it efficient and suitable for I/O-heavy applications. Understanding asynchronous programming is key to leveraging Node.js effectively.

Node.js is revolutionizing server-side development.
