| An Object.keys shim. Invoke its "shim" method to shim Object.keys if it is unavailable. | ||||
| Most common usage: | ||||
| ```js | ||||
| var keys = Object.keys || require('object-keys'); | ||||
| ``` | ||||
| ## Example | ||||
| ```js | ||||
| var keys = require('object-keys'); | ||||
| var assert = require('assert'); | ||||
| var obj = { | ||||
| a: true, | ||||
| b: true, | ||||
| c: true | ||||
| }; | ||||
| assert.deepEqual(keys(obj), ['a', 'b', 'c']); | ||||
| ``` | ||||
| ```js | ||||
| var keys = require('object-keys'); | ||||
| var assert = require('assert'); | ||||
| /* when Object.keys is not present */ | ||||
| delete Object.keys; | ||||
| var shimmedKeys = keys.shim(); | ||||
| assert.equal(shimmedKeys, keys); | ||||
| assert.deepEqual(Object.keys(obj), keys(obj)); | ||||
| ``` | ||||
| ```js | ||||
| var keys = require('object-keys'); | ||||
| var assert = require('assert'); | ||||
| /* when Object.keys is present */ | ||||
| var shimmedKeys = keys.shim(); | ||||
| assert.equal(shimmedKeys, Object.keys); | ||||
| assert.deepEqual(Object.keys(obj), keys(obj)); | ||||
| ``` | ||||
| ## Source | ||||
| Implementation taken directly from [es5-shim][es5-shim-url], with modifications, including from [lodash][lodash-url]. | ||||
| ## Tests | ||||
