Node.js is a JavaScript runtime environment that runs on the server side. It is open-source and free to use. Node.js is used to build scalable and high-performance web applications. Node.js is based on the V8 JavaScript engine, which is also used by Google Chrome. This means that Node.js can execute JavaScript code very quickly. Node.js uses an event-driven model, which means that it does not block when it is waiting for data from the network or a database. This makes Node.js very efficient for handling a large number of concurrent connections. Node.js is a popular choice for building real-time applications, such as chat applications and multiplayer games. It is also used to build APIs and microservices. Here are some of the benefits of using Node.js: Scalability: Node.js is very scalable, making it a good choice for large and complex applications. Performance: Node.js is very performant, making it a good choice for applications that need to handle a large number of concurrent connections. Event-driven: Node.js is event-driven, which makes it efficient for handling asynchronous tasks. Extensible: Node.js is extensible, making it easy to add new features and functionality. Open-source: Node.js is open-source, making it free to use and develop.
