ESLint v10.0.0 introduces major breaking changes including dropping support for Node.js versions below v20.19.0, complete removal of eslintrc configuration system, and a new config file lookup algorithm that starts from each linted file's directory. Key enhancements include JSX reference tracking for improved scope analysis, built-in TypeScript definitions for Espree and ESLint Scope, RuleTester improvements with assertion options and better error location reporting, and a new countThis option in the max-params rule. The release also removes deprecated context members and SourceCode methods, updates the Program AST node range to span entire source text, and requires jiti >= v2.2.0 for TypeScript config files.

<p>People - please ditch old and slow eslint and more to <a href="https://biomejs.dev/" target="_blank" rel="noopener nofollow">Biome</a> I’ve used eslint for many years and moved and it’s so much better (I have nothing to do with Biome, I’m just a dev sharing my experience).</p>
<p>All I want to to shrink eslint’s community in favor of Biome so the new faster better thing will become the norm</p>
