  Key features of Node.js Asynchronous and Non-blocking:  Node.js uses an event-driven, non-blocking I/O model. This allows it to handle concurrent connections efficiently, making it suitable for building highly scalable applications that require handling multiple requests concurrently without blocking the execution of other tasks. Single-threaded:  Although Node.js runs on a single thread, it utilizes an event loop and asynchronous programming to handle concurrent requests efficiently. It can handle thousands of concurrent connections with minimal resource usage, making it suitable for building real-time applications and microservices architectures. Cross-platform:  Node.js is cross-platform, which means that it can run on Windows, macOS, Linux, and other operating systems. This makes it a good choice for building applications that need to be deployed to a variety of environments. Open source:  Node.js is open source, which means that it is free to use and modi...

 Node JS Introduction Node.js is an open-source, server-side JavaScript runtime environment built on the V8 JavaScript engine. It allows developers to execute JavaScript code on the server-side, outside of a web browser.  A Node.js app runs in a single process, without creating a new thread for every request. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm. When Node.js performs an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will resume the operations when the response comes back. This allows Node.js to handle thousands of concurrent connections with a single server without introducing the burden of managing thread concurrency, which could be a significa...
