startsWith('18')which excluded React 19, causing it to fall back to the legacy useState+useLayoutEffect subscription path. This could cause tearing issues in concurrent rendering scenarios. Changed toparseInt(React.version) >= 18to correctly use useSyncExternalStore for React 18 and above.

7b38166Thanks @petyosi! - Replace ESLint and Prettier with oxlint and oxfmt for faster linting and formatting. Modernize TypeScript configuration withverbatimModuleSyntaxand ES2022 build targets.Source code changes are non-behavioral: stricter equality checks (
===/!==instead of truthiness),??instead of||for defaults, early returns instead of else blocks, self-closing JSX tags, and removal of unnecessary JSX fragments.LogLevelin react-virtuoso is changed from a TypeScript enum to a const object — the named exports (LogLevel.DEBUG, etc.) work identically, but enum reverse-mapping (LogLevel[0]) is no longer supported.
