An ECMAScript spec-compliant polyfill/shim for `globalThis`. Invoke its "shim" method to shim `globalThis` if it is unavailable.

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 proposal](https://github.com/tc39/proposal-global).

Most common usage:
```js
var globalThis = require('globalthis')(); // returns native globalThis if compliant
	/* or */
var globalThis = require('globalthis/polyfill')(); // returns native globalThis if compliant
```

## Example

```js
var assert = require('assert');

// the below function is not CSP-compliant, but reliably gets the
// global object in sloppy mode in every engine.
var getGlobal = Function('return this');

assert.equal(globalThis, getGlobal());
```

```js
/* when `globalThis` is not present */
var shimmedGlobal = require('globalthis').shim();
	/* or */
var shimmedGlobal = require('globalthis/shim')();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
```

```js
/* when `globalThis` is present */
var shimmedGlobal = require('globalthis').shim();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
```

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