`Number.isSafeInteger` shim/polyfill/replacement that works as far down as ES3.\n\nThis package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://tc39.es/ecma262/#sec-number.issafeinteger).\n\n## Getting started\n\n```sh\nnpm install --save number.issafeinteger\n```\n\n## Usage/Examples\n\n```js\nconsole.log(Number.isSafeInteger(-3)); // true\nconsole.log(Number.isSafeInteger(2 ** 53)); // false\nconsole.log(Number.isSafeInteger(2 ** 53 - 1)); // true\nconsole.log(Number.isSafeInteger(\"7\")); // false\n```\n\n## Tests\n\nClone the repo, `npm install`, and run `npm test`\n\n[package-url]: https://npmjs.org/package/number.issafeinteger\n[npm-version-svg]: https://versionbadg.es/es-shims/Number.isSafeInteger.svg\n[deps-svg]: https://david-dm.org/es-shims/Number.isSafeInteger.svg\n[deps-url]: https://david-dm.org/es-shims/Number.isSafeInteger\n[dev-deps-svg]: https://david-dm.org/es-shims/Number.isSafeInteger/dev-status.svg\n[dev-deps-url]: https://david-dm.org/es-shims/Number.isSafeInteger#info=devDependencies\n[npm-badge-png]: https://nodei.co/npm/number.issafeinteger.png?downloads=true\u0026stars=true\n[license-image]: https://img.shields.io/npm/l/number.issafeinteger.svg\n[license-url]: LICENSE\n[downloads-image]: https://img.shields.io/npm/dm/number.issafeinteger.svg\n[downloads-url]: https://npm-stat.com/charts.html?package=number.issafeinteger\n[codecov-image]: https://codecov.io/gh/es-shims/Number.isSafeInteger/branch/main/graphs/badge.svg\n[codecov-url]: https://app.codecov.io/gh/es-shims/Number.isSafeInteger/\n[actions-image]: https://img.shields.io/endpoint?url=https://github-actions-badge-u3jn4tfpocch.runkit.sh/es-shims/Number.isSafeInteger\n[actions-url]: https://github.com/es-shims/Number.isSafeInteger/actions\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fes-shims%2Fnumber.issafeinteger","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fes-shims%2Fnumber.issafeinteger","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fes-shims%2Fnumber.issafeinteger/lists"}
