# is-plain-object [](https://www.npmjs.com/package/is-plain-object) [](https://npmjs.org/package/is-plain-object) [](https://npmjs.org/package/is-plain-object) [](https://travis-ci.org/jonschlinkert/is-plain-object)
> Returns true if an object was created by the `Object` constructor.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save is-plain-object
```
Use [isobject](https://github.com/jonschlinkert/isobject) if you only want to check if the value is an object and not an array or null.
## Usage
```js
var isPlainObject = require('is-plain-object');
```
**true** when created by the `Object` constructor.
```js
isPlainObject(Object.create({}));
//=> true
isPlainObject(Object.create(Object.prototype));
//=> true
isPlainObject({foo: 'bar'});
//=> true
isPlainObject({});
//=> true
```
**false** when not created by the `Object` constructor.
```js
isPlainObject(1);
//=> false
isPlainObject(['foo', 'bar']);
//=> false
isPlainObject([]);
//=> false
isPlainObject(new Foo);
//=> false
isPlainObject(null);
//=> false
isPlainObject(Object.create(null));
//=> false
```
