ESLint major version upgrade from 8 to 9 is a breaking change. While the project already uses the ESLint 9 flat config format (eslint.config.js), there are several breaking changes in ESLint 9 that need verification: 1) Many formatting rules have been removed (use Prettier instead, which this project already does), 2) Some rule behaviors have changed, 3) Plugin compatibility - ensure all ESLint plugins (eslint-plugin-jsdoc, eslint-plugin-jsx-a11y, eslint-plugin-react, eslint-plugin-prettier) are compatible with ESLint 9. Testing the lint:js npm script in CI before merging is critical to ensure no unexpected breaking changes affect the build.
