eslint.config.js

"use strict";

// This is the internal ESLint config for this project itself – it’s not part of
// the eslint-config-prettier npm package. The idea here is to extend some
// sharable config from npm and then include the configs exposed by this package
// as an “eat your own dogfood” test. That feels like a good test, but
// complicates things a little sometimes.
//
// NOTE: Keep this file in sync with `./.eslintrc.js`!
