Node JS Intro

What is NodeJS?

NodeJS is nothing but JS runtime provider, before we can’t run JS outside the browser, but with the help of NodeJS now, we can run JS outside the browser window.

How NodeJS Invented?

NodeJS invented by Ryan Dahl, by using the open source of Google browser, every browser uses it’s own engine to run JavaScript like Google use v8 engine, Mozilla Firefox uses SpiderMonkey and many others for different browsers.

So Ryan Dahl takes the open source of google V8 engine and separate it from google and done some customisation like JS can’t run outside the browser, so what he does is he wrote C++ code and embedded with JavaScript and added some features that allows it to interact to with Operating System, and that’s how NodeJs Created

The diagram below shows how Ryan Dahl took the V8 engine from Chrome, used C++ to extend its capabilities, and built Node.js — enabling JavaScript to run outside of browsers.

So that’s how NodeJs was create in next we blog we will study about installation of NodeJS in windows
