Welcome to Part 4 of the JavaScript Machine Coding Interview Questions series! In this session, we’ll focus on comparing different approaches to solving problems. By analyzing various implementations, you’ll understand which solutions are cleaner, more scalable, and closer to what interviewers expect in real-world scenarios.

✅ What You’ll Learn in This Video:
✔️ Comparing a basic DOM-only implementation vs. a modular JavaScript approach
✔️ Understanding trade-offs between inline event handling and event delegation
✔️ Evaluating how different solutions handle state management (arrays, objects, or classes)
✔️ Assessing code readability, scalability, and maintainability
✔️ Learning interviewer expectations: clean code, reusability, and edge case handling

💡 Why This Step Matters:
🔹 Teaches you to critically analyze your own solutions and improve them
🔹 Prepares you for follow-up questions in interviews like “How would you optimize this?”
🔹 Builds the habit of writing production-ready, scalable code rather than quick hacks
