# has-property-descriptors <sup>[![Version Badge][npm-version-svg]][package-url]</sup> [![github actions][actions-image]][actions-url] [![coverage][codecov-image]][codecov-url] [![dependency status][deps-svg]][deps-url] [![dev dependency status][dev-deps-svg]][dev-deps-url] [![License][license-image]][license-url] [![Downloads][downloads-image]][downloads-url] [![npm badge][npm-badge-png]][package-url] Does the environment have full property descriptor support? Handles IE 8's broken defineProperty/gOPD. ## Example ```js var hasPropertyDescriptors = require('has-property-descriptors'); var assert = require('assert'); assert.equal(hasPropertyDescriptors(), true); // will be `false` in IE 6-8, and ES5 engines // Arrays can not have their length `[[Defined]]` in some engines assert.equal(hasPropertyDescriptors.hasArrayLengthDefineBug(), false); // will be `true` in Firefox 4-22, and node v0.6 ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` [package-url]: https://npmjs.org/package/has-property-descriptors [npm-version-svg]: https://versionbadg.es/inspect-js/has-property-descriptors.svg [deps-svg]: https://david-dm.org/inspect-js/has-property-descriptors.svg [deps-url]: https://david-dm.org/inspect-js/has-property-descriptors [dev-deps-svg]: https://david-dm.org/inspect-js/has-property-descriptors/dev-status.svg [dev-deps-url]: https://david-dm.org/inspect-js/has-property-descriptors#info=devDependencies [npm-badge-png]: https://nodei.co/npm/has-property-descriptors.png?downloads=true&stars=true [license-image]: https://img.shields.io/npm/l/has-property-descriptors.svg [license-url]: LICENSE [downloads-image]: https://img.shields.io/npm/dm/has-property-descriptors.svg [downloads-url]: https://npm-stat.com/charts.html?package=has-property-descriptors [codecov-image]: https://codecov.io/gh/inspect-js/has-property-descriptors/branch/main/graphs/badge.svg [codecov-url]: https://app.codecov.io/gh/inspect-js/has-property-descriptors/ [actions-image]: https://img.shields.io/endpoint?url=https://github-actions-badge-u3jn4tfpocch.runkit.sh/inspect-js/has-property-descriptors [actions-url]: https://github.com/inspect-js/has-property-descriptors/actions
