# I Created a Pagination Challenge… And AI Missed the Real Problem

📄

Pagination looks simple.

Page → limit → slice → done.

That’s what I thought.

So I created a small challenge on VibeCode Arena.

And things got interesting.

🚨 The Problem

The logic works perfectly… on static data.

But real systems are not static.

Data keeps changing.

Users keep adding and removing items.

🧠 What Goes Wrong?

In real-world scenarios:

• New data gets inserted
• Old data gets deleted
• Users refresh pages

And suddenly:

👉 You see duplicate data

👉 Or you miss some records

This is a very common production bug.

🤯 What I Observed

When AI models tried this:

• Most gave basic slice-based logic
• Some didn’t consider dynamic data
• Very few suggested cursor-based pagination

The code works.

But the system is unreliable.

🔥 Try It Yourself

I created this challenge to test real-world API thinking.

👉 Try it here:

Can you:

• Prevent duplicate records?
• Handle dynamic data?
• Design a scalable pagination system?

💡 Final Thought

Pagination is not about slicing data.

It’s about making sure users see the right data at the right time.

Would you trust AI to design API-level logic like this?
