    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

# propertyDescriptorsIn

[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] <!-- [![dependencies][dependencies-image]][dependencies-url] -->

> Return an object's own and inherited [property descriptors][@stdlib/utils/property-descriptors].

<section class="installation">

## Installation

```bash
npm install @stdlib/utils-property-descriptors-in
```

</section>

<section class="usage">

## Usage

```javascript
var propertyDescriptorsIn = require( '@stdlib/utils-property-descriptors-in' );
```

#### propertyDescriptorsIn( obj )

Returns an object's own and inherited [property descriptors][@stdlib/utils/property-descriptors].

```javascript
var obj = {
    'a': 1,
    'b': 2
};

var desc = propertyDescriptorsIn( obj );
// returns { 'a': {...}, 'b': {...}, ... }
```

</section>

<!-- /.usage -->

<section class="notes">

## Notes

-   In contrast to the built-in `Object.getOwnPropertyDescriptors()`, if provided `null` or `undefined`, the function returns an empty `object`, rather than throwing an error.

</section>

<!-- /.notes -->

<section class="examples">

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var defineProperty = require( '@stdlib/utils-define-property' );
var propertyDescriptorsIn = require( '@stdlib/utils-property-descriptors-in' );

function Foo() {
    this.beep = 'boop';
    this.a = {
        'b': 'c'
    };
    defineProperty( this, 'baz', {
        'value': 'qux',
        'configurable': true,
        'writable': true,
        'enumerable': false
    });
    return this;
}

Foo.prototype.foo = [ 'bar' ];

var obj = new Foo();
var desc = propertyDescriptorsIn( obj );

console.log( desc );
// => { 'beep': {...}, 'a': {...}, 'baz': {...}, 'foo': {...}, ... }
```
