In this video, we implement the MyCalendar JavaScript project — a perfect coding challenge to understand how to handle interval overlaps and prevent double bookings.

This problem is based on LeetCode 729: My Calendar I, where we design a booking system that allows adding new events only if they do not overlap with existing ones.

You’ll learn:
✅ How to check overlapping intervals in JavaScript
✅ How to design a class with methods in JavaScript
✅ Step-by-step logic and explanation of each booking condition

💻 Code Explanation:
We use simple comparisons to ensure that the new event does not intersect with any existing one, returning true if added successfully and false otherwise.

If you’re preparing for JavaScript coding interviews, this problem will help you understand object-oriented design, logic building, and interval management.
