     27 ## Usage
     28 
     29 ```javascript

     34 
     35 Returns an object's own and inherited [property descriptors][@stdlib/utils/property-descriptors].
     36 
     37 ```javascript
     38 var obj = {
     39     'a': 1,
     40     'b': 2
     41 };
     42 
     43 var desc = propertyDescriptorsIn( obj );
     44 // returns { 'a': {...}, 'b': {...}, ... }

     53 ## Notes
     54 
     55 -   In contrast to the built-in `Object.getOwnPropertyDescriptors()`, if provided `null` or `undefined`, the function returns an empty `object`, rather than throwing an error.
