What Is Node JS?

Node JS is a Server-Side platform that is built on Google Chrome's JavaScript Engine (V8 Engine). The Node JS library was developed by Ryan Dahl in 2009 and its current version as of the time of this writing is v 13.0.1.

Node.js is a program that is built on Google Chrome's JavaScript runtime engine to enable software developers to easily build very fast and scalable network applications. Node.js makes use of an event-driven, non-blocking Input-Output model that makes it lightweight, very effective and perfect for real-time web applications that highly depend on data that run across multiple devices.

Node.js is an Open-Source, multi-platform development environment that is used for developing server-side and Networking Applications. Node.js applications are generally written in JavaScript and they can be run inside the Node.js runtime on Microsoft Windows, OS X and the flavors of Linux.

The Node.js library also offers a rich set of various JavaScript Libraries and Modules that makes easy, the process of developing easily scalable web applications using Node.js to a great extent.

Features Of Node JS

Node JS has so many features and characteristics. The following are some of the important features that make Node.js to become the first choice of software developers.

1. Asynchronous and Event-Driven: All APIs found in the Node.js library are asynchronous, which means that they are non-blocking. It basically means that a web server that is based or built upon Node JS does not wait for an API to return request data. The server goes straight to the next API after requesting the API resource and a notification tool of Events in Node.js helps the webserver to get a response from the API that was called previously.

2. Very Fast: Node JS library, Being built on Google Chrome's V8 JavaScript Engine, is very fast in executing the code that is being run on it.

3. Single-Threaded but Highly Scalable: Node.js makes use of a single-threaded model that includes looping of events. The event mechanism of Node JS helps the server to respond in a non-blocking way and it makes the server highly scalable which is opposing to traditional web servers that use the threading feature to create limited threads that handle requests. Node.js web servers use a single-threaded program and the same single-threaded program can provide better function and service to a much larger number of requests than conventional web servers like the Apache HTTP Server.

4. No Buffering: Node.js applications does not buffer any data. Its applications simply output the data in pieces.

5. License: The Node JS library is released under the MIT license.
