```

## Usage

```js
import isPlainObject from '@stackline/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
