> 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]);
|
