Day 43/200: Callback Functions in JavaScript 🚀
I’m on a 200-day journey to become a full-proof web developer, and today I learned about Callback Functions one of the core concepts behind async programming in JavaScript.

A callback is a function passed into another function to be executed later essential for tasks like animations, API calls, timers, event listeners, and more 💡

In this short, I explained:
✅ What a callback function is
🔄 Why callbacks are used
⚙️ Real examples (setTimeout, event listeners, custom functions)
🧠 How callbacks help control program flow

In this series, I’ll be improving my skills daily in:
✅ Frontend (HTML, CSS, JavaScript, React, Next.js)
✅ Backend (Node.js, Express, Databases)
✅ DSA (Problem Solving & Algorithms)
✅ AI/ML in Web Development
✅ Real Projects & Deployments
