Introduction of node JS What is node js?

NodeJs is a JavaScript runtime built on chrome V8 javascript engine, where it enables JavaScript to run outside a browser. It is built on V8 JavaScript, a motor that Google developed for its Chrome OS. Node Js is extremely beloved because of its non blocking model of I/O event—driven that allows the framework to handle many connection instantly and it does not stop the main thread. It also means that the data structure is suitable to be used in applications that require frequent updates such as chats, online gaming and streaming application. This article will introduce what node js is and its characteristics, advantages, disadvantages, and employment scenarios.

Some of these key features of Node JS include the following;

Asynchronous programming: Node js works asynchronously or you could also say it follows the event-driven model of the program which allows it to run several tasks at one time without interfering with the primary flow. This improves efficiency and effectiveness and thus the scalability.

Event-driven I/O: Node js is based on the event driven I/O model and callbacks call back when I/O operations are complete. This makes it possible for the system to manage several requests at the same time.

Single-threaded event loop: Node js utilizes the single threaded model based upon event loop for handling the asynchronous operations. This makes the programming model more simplified and at the same time assist in reducing the cost that is incurred while establishing and managing threads.

Cross-platform compatibility: Node js supports all windows, Mac operating systems as well as Linux operating systems. This of course makes it a suitable tool which can be applied in various development environments.

Rich ecosystem: Responding to the advantage of using Node js, the language has a massive network of modules and libraries it comes with through npm (Node Package Manager). These are easy to install and use hence enables one to incorporate more functions into ones
