Understanding How Node.js Works :

⚙️ Node.js and C++

• Node.js is written in C++ because it’s built on top of Google’s V8 engine, which itself is written in C++.
• V8 is a high-performance JavaScript engine used in Chrome, and it's also open-source and extremely fast.
• Thanks to V8, JavaScript code can be executed quickly by compiling it into machine code.

📜 ECMAScript & JavaScript Engines

• ECMAScript (ES) is the standard that JavaScript is based on.
• A JavaScript engine is the program that converts JavaScript into machine language — similar to how JVM works for Java.
• Popular JS engines include V8 (Chrome/Node.js), SpiderMonkey (Firefox), and JavaScriptCore (Safari).

🤝 JavaScript & C++ in Node.js

• JavaScript in Node.js can interact with C++ through bindings. Some of the Node.js core functionality is actually C++ code wrapped in JS.
• This gives JavaScript access to powerful C++ features while maintaining the flexibility of JS.
• C++ offers more low-level control, while JavaScript is designed primarily for web applications.

🚀 What Is Node.js?

• Node.js is a runtime that lets us run JavaScript outside the browser, using V8 under the hood.
• It allows developers to write server-side applications using JavaScript.
• One key reason for Node.js’s existence is to let us use the same language (JS) on both the frontend (browser) and the backend (server).

🔧 Why Node.js Is Awesome

Node.js provides tools and features that solve common development challenges:

• ✅ Code Organization: Better ways to organize code into reusable modules.
