🚀 True O(1) Memory

Maintains constant memory regardless of dataset size through intelligent caching and sliding window algorithms.

📏 Variable Heights

No pre-calculation required. Heights are measured on-demand with automatic caching for optimal performance.

🎯 Element-Based Positioning

Innovative element + offset positioning system eliminates complex pixel calculations and improves accuracy.

⚡ Incremental DOM Updates

Only creates/removes elements at viewport edges. No repositioning or GPU transforms needed.

🖱️ Native Scrollbar Integration

Bidirectional sync with native scrollbars provides familiar UX while maintaining virtual scrolling efficiency.

🔧 Framework Agnostic

Works with Vanilla JS, Vue, Angular, React, or any framework. Simple integration with full TypeScript support.
