Package - object-keys

#object-keys

An Object.keys shim. Invoke its "shim" method to shim Object.keys if it is unavailable.

Most common usage:

var keys = Object.keys || require('object-keys');

Example

var keys = require('object-keys');
var assert = require('assert');
var obj = {
	a: true,
	b: true,
	c: true
};

assert.deepEqual(keys(obj), ['a', 'b', 'c']);

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));

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));
