Build Auto Complete Search Bar in React JS | Frontend Machine Coding | Episode 3

🚀 Welcome to Episode 3 of the Frontend Machine Coding Interview Masterclass, where we’re building an Auto Complete Search Bar in React JS — the kind of component you might be asked to implement in a frontend interview or system design round.

In this episode, you’ll learn how to:
✅ Build an intuitive, responsive search bar using React
✅ Filter and display suggestions based on user input
✅ Use debouncing to optimise performance
✅ Add keyboard navigation and accessibility
✅ Handle edge cases like empty or invalid input
✅ Create a reusable and customizable component

📌 This project is perfect for sharpening your UI design, React state management, and problem-solving skills — especially for interviews at top tech companies.
