Node.js is a JavaScript runtime built on Chrome's V8 engine, designed for building scalable network applications. It uses an event-driven, non-blocking I/O model, making it lightweight and efficient for real-time applications that require high concurrency.
What are the key features of Node.js?
Key features of Node.js include its event-driven architecture, non-blocking I/O operations, single-threaded nature, and a rich ecosystem of modules and libraries available through npm.
How does Node.js handle asynchronous operations?
Node.js handles asynchronous operations using callbacks, promises, and the async/await syntax, allowing it to efficiently manage multiple I/O operations without blocking the main execution thread.
What are common use cases for Node.js?
Common use cases for Node.js include building real-time applications such as chat applications, APIs for web and mobile applications, streaming services, and microservices architecture.
