| 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)); | |
| ``` | |
