An ES2015 mostly-spec-compliant `Reflect.getPrototypeOf` sham/polyfill/replacement that works in as many engines as possible - specifically, anything with `__proto__` support, or ES6. Built-in types will also work correctly in older engines.

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://www.ecma-international.org/ecma-262/5.1/).

## Example

```js
var getPrototypeOf = require('reflect.getprototypeof');
var assert = require('assert');

assert.throws(() => getPrototypeOf(true));
assert.throws(() => getPrototypeOf(42));
assert.throws(() => getPrototypeOf(''));
assert.equal(getPrototypeOf(/a/g), RegExp.prototype);
assert.equal(getPrototypeOf(new Date()), Date.prototype);
assert.equal(getPrototypeOf(function () {}), Function.prototype);
assert.equal(getPrototypeOf([]), Array.prototype);
assert.equal(getPrototypeOf({}), Object.prototype);
```

```js
var getPrototypeOf = require('reflect.getprototypeof');
var assert = require('assert');
/* when Reflect or Reflect.getPrototypeOf is not present */
if (typeof Reflect === 'object') { delete Reflect.getPrototypeOf; }
delete globalThis.Reflect;
var shimmed = getPrototypeOf.shim();
assert.equal(shimmed, getPrototypeOf.getPolyfill());

assert.throws(() => Reflect.getPrototypeOf(true));
assert.throws(() => Reflect.getPrototypeOf(42));
assert.throws(() => Reflect.getPrototypeOf(''));
assert.equal(Reflect.getPrototypeOf(/a/g), RegExp.prototype);
assert.equal(Reflect.getPrototypeOf(new Date()), Date.prototype);
assert.equal(Reflect.getPrototypeOf(function () {}), Function.prototype);
assert.equal(Reflect.getPrototypeOf([]), Array.prototype);
assert.equal(Reflect.getPrototypeOf({}), Object.prototype);
```

```js
var getPrototypeOf = require('reflect.getprototypeof');
var assert = require('assert');
/* when Reflect.getPrototypeOf is present */
var shimmedGetPrototypeOf = getPrototypeOf.shim();
assert.equal(shimmedGetPrototypeOf, Reflect.getPrototypeOf);
assert.equal(Reflect.getPrototypeOf([]), Array.prototype);
```
