Node Js

What is the Node JS ?

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side. Node.js has an event-driven architecture capable of asynchronous I/O. Node.js is intended to run on a dedicated HTTP server and to employ a single thread with one process at a time. Node.js applications are events-based and run asynchronously. Code built on the Node platform does not follow the traditional model of receive, process, send, wait, receive. Instead, Node processes incoming requests in a constant event stack and sends small requests one after the other without waiting for responses.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.node.js is not a programming language but a minimal framework. Language is Javascript. So the easiest path for you is node.js but such framework would only solve part of your problem, and on the downside could give you bad habits (not everything needs to be event driven).

A node is a basic unit used in computer science. Nodes are devices or data points on a larger network. Devices such as a personal computer, cell phone, or printer are nodes. When defining nodes on the internet, a node is anything that has an IP address. Node.jsĀ® is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node is a runtime or environment. It is not a framework. People (I feel) often get this wrong because frameworks like express are ubiquitous with node.One of the major advantages of Node.js, according to its creator Ryan Dahl, is that it does not block input/output (I/O). Some developers are highly critical of Node.js and point out that if a single process requires a significant number of CPU cycles, the application will block and that the blocking can crash the application. Proponents of the Node.js model claim that CPU processing time is less of a concern because of the high number of small processes that Node code is based on.
