Widest Vertical Area Between Two Points | JavaScript Easy Explanation | LeetCode Problem Solved

In this video, we solve the Widest Vertical Area Between Two Points problem in JavaScript, step-by-step.
We find the maximum vertical gap (width) between points on a 2D plane such that no points exist within that area.

📊 Approach Summary:
1️⃣ Extract all x-coordinates from the given points.
2️⃣ Sort them in ascending order.
3️⃣ Find the maximum difference between consecutive x-values.

This solution has a time complexity of O(n log n) — perfect for large inputs up to 10⁵ points!

💡 Example Inputs & Outputs:

Input: points = [[8,7],[9,9],[7,4],[9,7]] Output: 1 Input: points = [[3,1],[9,0],[1,0],[1,4],[5,3],[8,8]] Output: 3
