> Check if a value is a plain object

An object is plain if it's created by either `{}`, `new Object()`, or `Object.create(null)`.

## Install

```
$ npm install is-plain-obj
```

## Usage

```js
const isPlainObject = require('is-plain-obj');

isPlainObject({foo: 'bar'});
//=> true

isPlainObject(new Object());
//=> true

isPlainObject(Object.create(null));
//=> true

isPlainObject([1, 2, 3]);
//=> false

class Unicorn {}
isPlainObject(new Unicorn());
//=> false
```
