🌐 How to Make a Server

⚛️ What is a Server?

A server is a program that:

Listens for client requests (like from your React app 🧠)

Processes data 💾

Sends responses back (like JSON, files, or HTML)

In modern web apps, we usually build servers using Node.js and Express.js because: ✅ It’s JavaScript-based (same language as React)

• ✅ It’s fast and lightweight

• ✅ It integrates easily with databases like MongoDB or MySQL
