There are several reasons why Node.js has become popular:
- Node.js has a large and active community of developers, with many open-source libraries and frameworks available for building server-side applications. These libraries and frameworks make it easier to build and deploy applications, as well as add features such as authentication and database access.
- Node.js is designed for building scalable, high-performance applications. It uses an event-driven, non-blocking I/O model, which makes it well-suited for building applications that need to handle a large number of concurrent connections.
- Node.js has strong support for building real-time applications, such as chat and collaboration tools, thanks to its event-driven architecture and built-in support for WebSockets.
Overall, Node.js is a popular runtime environment for building server-side applications due to its wide adoption, active developer community, scalability, and support for building real-time applications.
