NWSAPI is a fast CSS Selectors API engine written in pure JavaScript, built to aim for Selectors Level 4 conformance. It provides functions to parse and compile CSS selector strings for DOM selection and matching, and it can be used in browsers (as a global `NW.Dom`), or in headless environments and Node.js (as a CommonJS module).
