Why NodeJS is a must?

Introduction

JavaScript’s rising popularity has brought with it a lot of changes, and the face of web development today is dramatically different. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine just several years ago or were encapsulated within sandboxed environments like Flash or Java Applets.

How does it work?

What it really means is that Node.js is not a silver-bullet new platform that will dominate the web development world. Instead, it’s a platform that fills a particular need.

It is a used as backend service where javascript works on the server-side of the application. This way javascript is used on both frontend and backend. Node.js runs on chrome v8 engine which converts javascript code into machine code, it is highly scalable, lightweight, fast, and data-intensive.
