## README

# is-plain-obj

> 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
import isPlainObject from 'is-plain-obj';
import {runInNewContext} from 'node:vm';

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

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

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

// This works across realms
isPlainObject(runInNewContext('({})'));
//=> true

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

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

isPlainObject(Math);
//=> false
```
