# propertyDescriptorsIn

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

<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.

## 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': {...}, ... }
```
