## What it is
A highly performant DOM-based web table/grid library written in TypeScript that can render millions of rows at constant time complexity. It uses web workers with shared array buffers for off-thread sorting and filtering, custom virtualization, and its own event loop to maintain 120fps even under heavy load.

## Use cases
- render millions of rows in a browser table without lag
- sort and filter large datasets while scrolling at 120fps
- build a financial data grid that never drops frames
- display huge log tables in a web app
- smooth scrolling data grid on mobile phones
- replace slow virtualized table libraries with a faster alternative

## When to choose
- you need to display or interact with very large datasets (hundreds of thousands to millions of rows) in the browser
- you require consistent high frame rates while sorting, filtering, and scrolling simultaneously
- browser pixel-height limits of standard virtualization break your current table
- you need performant scrolling on mobile devices

## When to avoid
- you need a mature, feature-complete grid with column resizing, custom cell renderers, and full column sort/filter support (still on the TODO list)
- your primary target is iPhone Safari with its low memory limits
- you need a batteries-included enterprise data grid with built-in editing, grouping, or export features
- you prefer a well-documented library with a large community and ecosystem

## Facets
- artifact type: library
- maturity: experimental
