NodeJS
Node JS:
Since its inception in 2009, NodeJS (or simply ‘Node’) has steadily grown in popularity. Node is a scalable and versatile program builder that uses an event-driven JavaScript runtime that isn’t always up to date.
Node JS is a cross-platform, open-source back-end JavaScript runtime environment that uses the V8 engine to execute JavaScript code outside of an internet browser. Node.js allows developers to utilize JavaScript to create control tools and server-side programming, which includes running programs on the website before sending the site to the browser window. As a result, Node.js promotes a “JavaScript anywhere” paradigm, bringing web application development together around a single programming language instead of separate languages for device and customer scripts. Node.js is a server-side framework built on the JavaScript Engine in Google Chrome (V8 Engine).
In the year 2009, Ryan Dahl created NodeJS. NodeJS is a framework for efficiently creating fast, and scalable network applications based on Chrome’s JavaScript runtime. NodeJS is lightweight and efficient because of its event-driven, non-blocking I/O approach, which is ideal for data-intensive real-time applications that operate across multiple devices. NodeJS also comes with a large library of JavaScript components, which greatly facilitates the building of Node.js web applications. NodeJS is a truly open cross-platform runtime environment for developing server-side and networking applications. NodeJS apps are written in JavaScript and run on OS X, Microsoft Windows, and Linux using the NodeJS runtime.
NodeJS is an open source development environment for server-side execution of JavaScript code. Node is commonly used for real world applications like chatting, news sites, and web push notifications and is useful for designing apps that demand a secured connection from the browser to the site. NodeJS is designed to run on a specialized HTTP server and to run a single process at a time in a single thread. NodeJS’s apps are event-driven and run in the background. The usual model of receive, process, transmit, await, receive is not followed by code written on the Node framework. Instead of waiting for responses, Node processes incoming requests in a continuous action loop and makes tiny requests sequentially. This is a departure from traditional approaches, which execute larger, more sophisticated processes and multiple processes at the same time, with every loop awaiting its result until continuing on. One of Node.js’ biggest benefits is that it doesn’t obstruct input/output (I/O). Certain programmers are harsh critics of Node.js, claiming that if a single method consumes numerous CPU cycles, the program may stop, and the stopping can cause the program to collapse.
Because of the large number of tiny processes that Node programming is constructed on, proponents of the Node.js approach believe that CPU processing efficiency is less of an issue..
