Profile

I built the fastest React virtualisation library. The core is written in Rust and compiled to WebAssembly.Live Demo: https://warper.tech10 million rows at 120+ FPS. No lag. No dropped frames.Existing libraries like react-window and react-virtuoso hit walls at scale. They rely on JavaScript binary search and O(n) scans for variable heights. Warper is different.The engine uses:- Fenwick trees for O(log n) variable-height lookups - O(1) arithmetic for fixed-height items - Zero-copy typed arrays between WASM and JS - Pre-allocated memory pools with zero GC during scrollBenchmarks on M1 MacBook Pro with 1M rows: Warper hits 119 FPS. react-virtuoso drops to 58 FPS. At 10M rows Warper stays at 118

Warper – The fastest React virtualization library, built with Rust/WASM is positioned in show hn launch, a segment that rewards a clear, focused offering.

It is recorded at the Show HN launch stage.
