Node.js is an open-source, cross-platform runtime environment that allows developers to run JavaScript code outside a web browser. Here are some key points about Node.js: JavaScript Runtime : Node.js uses the V8 JavaScript engine, which is the same engine used by Google Chrome, to execute JavaScript code on the server side. Non-blocking I/O : Node.js is designed with non-blocking, event-driven architecture. This makes it efficient and suitable for data-intensive real-time applications that run across distributed devices. Single-threaded Event Loop : Despite being single-threaded, Node.js can handle many connections concurrently by using an event-driven, non-blocking I/O model, which helps in managing high throughput. NPM (Node Package Manager) : Node.js comes with NPM, the largest ecosystem of open-source libraries and packages, which simplifies the development process by allowing developers to easily share and reuse code. Popular Use Cases : Node.js is commonly used for develop...
