Returns an object's own and inherited property descriptors.
var obj = {
'a': 1,
'b': 2
};
var desc = propertyDescriptorsIn( obj );
// returns { 'a': {...}, 'b': {...}, ... }
- In contrast to the built-in
Object.getOwnPropertyDescriptors()
, if providednull
orundefined
, the function returns an emptyobject
, rather than throwing an error.
