Pull Request Overview

The PR removes several polyfill dependencies in favor of native built-in APIs and cleans up related code and configs.

• Replaced safe-regex-test, string.prototype.includes, object.entries, object.fromentries, and object.assign imports with native RegExp.prototype.test, String.prototype.includes, Object.entries, Object.fromEntries, and Object.assign.
• Removed unnecessary ESLint disable comments and updated configs (Babel preset, ESLint resolver, ignored folders).
• Updated scripts, mocks, and tests to use built-ins and cleaned up package.json devDependencies.

• Use Number.isNaN(value) instead of the global isNaN to avoid unexpected coercion and satisfy strict lint rules.

if (isNaN(value) || value <= 0) {

src/rules/aria-proptypes.js:49

• Prefer using Number.isNaN(Number(value)) for a more accurate NaN check and to avoid reliance on the global isNaN.

return typeof value !== 'boolean' && isNaN(Number(value)) === false;
