Nodejs introduction

A common misconception is that Node.js is a JavaScript library or framework. It's neither. Node.js is a runtime environment, a distinct entity that enables JavaScript execution outside the browser.

let’s consider how browsers function to run javaScript

1.chrome = v8 engine

2.firefox = safariMonkey

3.safari = javascriptCore

Ryan Dahl's groundbreaking innovation was to embed the Chrome V8 engine within a C++ application. This integration allowed JavaScript to interact directly with the operating system, file system, and network, breaking free from the browser's sandbox. Consequently, Node.js provides a robust runtime environment for JavaScript, enabling server-side development, command-line tools, and much more.

in summary nodeJs = embedded (chrome V8 engine + C++)
