#object.getownpropertydescriptors <sup>[![Version Badge][npm-version-svg]][package-url]</sup> [![Build Status][travis-svg]][travis-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] [![browser support][testling-svg]][testling-url] An ES2017 spec-compliant shim for `Object.getOwnPropertyDescriptors` that works in ES5. Invoke its "shim" method to shim `Object.getOwnPropertyDescriptors` if it is unavailable, and if `Object.getOwnPropertyDescriptor` is available. This 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://github.com/tc39/ecma262/pull/582). ## Example ```js var getDescriptors = require('object.getownpropertydescriptors'); var assert = require('assert'); var obj = { normal: Infinity }; var enumDescriptor = { enumerable: false, writable: false, configurable: true, value: true }; var writableDescriptor = { enumerable: true, writable: true, configurable: true, value: 42 }; var symbol = Symbol(); var symDescriptor = { enumerable: true, writable: true, configurable: false, value: [symbol] }; Object.defineProperty(obj, 'enumerable', enumDescriptor); Object.defineProperty(obj, 'writable', writableDescriptor); Object.defineProperty(obj, 'symbol', symDescriptor); var descriptors = getDescriptors(obj); assert.deepEqual(descriptors, { normal: { enumerable: true, writable: true, configurable: true, value: Infinity }, enumerable: enumDescriptor, writable: writableDescriptor, symbol: symDescriptor }); ``` ```js var getDescriptors = require('object.getownpropertydescriptors'); var assert = require('assert'); /* when Object.getOwnPropertyDescriptors is not present */ delete Object.getOwnPropertyDescriptors; var shimmedDescriptors = getDescriptors.shim(); assert.equal(shimmedDescriptors, getDescriptors); assert.deepEqual(shimmedDescriptors(obj), getDescriptors(obj)); ``` ```js var getDescriptors = require('object.getownpropertydescriptors'); var assert = require('assert'); /* when Object.getOwnPropertyDescriptors is present */ var shimmedDescriptors = getDescriptors.shim(); assert.notEqual(shimmedDescriptors, getDescriptors); assert.deepEqual(shimmedDescriptors(obj), getDescriptors(obj)); ``` ## Tests Simply clone the repo, `npm install`, and run `npm test` [package-url]: https://npmjs.org/package/object.getownpropertydescriptors [npm-version-svg]: http://versionbadg.es/ljharb/object.getownpropertydescriptors.svg [travis-svg]: https://travis-ci.org/ljharb/object.getownpropertydescriptors.svg [travis-url]: https://travis-ci.org/ljharb/object.getownpropertydescriptors [deps-svg]: https://david-dm.org/ljharb/object.getownpropertydescriptors.svg [deps-url]: https://david-dm.org/ljharb/object.getownpropertydescriptors [dev-deps-svg]: https://david-dm.org/ljharb/object.getownpropertydescriptors/dev-status.svg [dev-deps-url]: https://david-dm.org/ljharb/object.getownpropertydescriptors#info=devDependencies [testling-svg]: https://ci.testling.com/ljharb/object.getownpropertydescriptors.png [testling-url]: https://ci.testling.com/ljharb/object.getownpropertydescriptors [npm-badge-png]: https://nodei.co/npm/object.getownpropertydescriptors.png?downloads=true&stars=true [license-image]: http://img.shields.io/npm/l/object.getownpropertydescriptors.svg [license-url]: LICENSE [downloads-image]: http://img.shields.io/npm/dm/object.getownpropertydescriptors.svg [downloads-url]: http://npm-stat.com/charts.html?package=object.getownpropertydescriptors
