verified May 1, 2026

A CSS selector compiler/engine that turns CSS selectors into functions for testing and querying DOM elements. Current stable version is 2.x (v1.3.0-rc0 is a pre-release of a UMD build). It uses right-to-left execution for efficient O(n) performance, unlike left-to-right engines like Sizzle. Features full CSS3 selectors, partial jQuery extensions, and uses domhandler/domutils as default DOM adapter. Released regularly via npm; TypeScript types included since v1.3.0. Key differentiator: performance through right-to-left compilation and a function-stack approach.
