Mon - Sat 9.00 - 19.00. Sunday CLOSED 
Welcome to Part 19 of the JavaScript Machine Coding Interview Questions series! In this session, we’ll solve Question 15, a practical coding challenge that sharpens your logical thinking, coding efficiency, and ability to write clean, production-ready JavaScript solutions. This problem is slightly more advanced and mirrors real interview scenarios you may face.
✅ What You’ll Learn in This Video:
✔️ Breaking down the coding problem into clear logical steps
✔️ Applying modern JavaScript concepts (Set, Map, reduce, async patterns, etc.)
✔️ Handling tricky edge cases gracefully
✔️ Writing modular, reusable, and testable code
✔️ Optimizing solutions with time and space complexity in mind
💡 Why This Step Matters:
🔹 Prepares you for mid-to-advanced coding interviews
🔹 Helps you transition from basic algorithmic solutions to production-level coding
🔹 Shows interviewers your ability to think critically about performance and scalability
🔹 Builds confidence in solving real-world coding challenges under pressure
