Get and robustly cache all JS language-level intrinsics at first require time.
See the syntax described [in the JS spec](https://tc39.es/ecma262/#sec-well-known-intrinsic-objects) for reference.
## Example
```js
var GetIntrinsic = require('get-intrinsic');
var assert = require('assert');
// static methods
assert.equal(GetIntrinsic('%Math.pow%'), Math.pow);
assert.equal(Math.pow(2, 3), 8);
assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
delete Math.pow;
assert.equal(GetIntrinsic('%Math.pow%')(2, 3), 8);
// instance methods
var arr = [1];
assert.equal(GetIntrinsic('%Array.prototype.push%'), Array.prototype.push);
assert.deepEqual(arr, [1]);
arr.push(2);
assert.deepEqual(arr, [1, 2]);
GetIntrinsic('%Array.prototype.push%').call(arr, 3);
assert.deepEqual(arr, [1, 2, 3]);
delete Array.prototype.push;
GetIntrinsic('%Array.prototype.push%').call(arr, 4);
assert.deepEqual(arr, [1, 2, 3, 4]);
// missing features
delete JSON.parse; // to simulate a real intrinsic that is missing in the environment
assert.throws(() => GetIntrinsic('%JSON.parse%'));
assert.equal(undefined, GetIntrinsic('%JSON.parse%', true));
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`
## Security

==================
* Using "foreach" instead of my own shim.
* Removing "tap"; I'll just wait for "tape" to fix its node 0.10 bug.
0.1.2 / 2013-04-03
==================
* Adding dependency status; moving links to an index at the bottom.
* Upgrading is-extended; version 0.1.2
* Adding an npm version badge.
0.1.1 / 2013-04-01
==================
* Adding Travis CI.
* Bumping the version.
* Adding indexOf since IE sucks.
* Adding a forEach shim since older browsers don't have Array#forEach.
* Upgrading tape - 0.3.2 uses Array#map
* Using explicit end instead of plan.
* Can't test with Array.isArray in older browsers.
* Using is-extended.
* Fixing testling files.
* JSHint/JSLint-ing.
* Removing an unused object.
* Using strict mode.
0.1.0 / 2013-03-30
==================
* Changing the exports should have meant a higher version bump.
* Oops, fixing the repo URL.
* Adding more tests.
* 0.0.2
* Merge branch 'export_one_thing'; closes [#1](https://github.com/ljharb/object-keys/issues/1)
* Move shim export to a separate file.

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
Simply clone the repo, `npm install`, and run `npm test`

[![coverage][codecov-image]][codecov-url]
[![License][license-image]][license-url]

Robustly get an object's own property keys (strings and symbols), including non-enumerables when possible.
## Getting started
```sh
npm install --save own-keys
```
## Usage/Examples
```js
var ownKeys = require('own-keys');
var assert = require('assert');
assert.deepEqual(ownKeys({ a: 1, b: 2 }), ['a', 'b']);
assert.deepEqual(ownKeys([1, 2, 3]), [0, 1, 2, 'length']);
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`

Push an array of items into an array, while being robust against prototype modification.
## Getting started
```sh
npm install --save safe-push-apply
```
## Usage/Examples
```js
var safePushApply = require('safe-push-apply');
var assert = require('assert');
var arr = [1, 2, 3];
var orig = Array.prototype[Symbol.iterator];
delete Array.prototype[Symbol.iterator];
assert.throws(() => {
try {
arr.push(...[3, 4, 5]);
} finally {
Array.prototype[Symbol.iterator] = orig;
}
}, 'array is not iterable anymore');
delete Array.prototype.push;
safePushApply(arr, [3, 4, 5]);
assert.deepEqual(arr, [1, 2, 3, 3, 4, 5]);
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`
