propertyDescriptorsIn

Return an object's own and inherited property descriptors.

Usage

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

propertyDescriptorsIn( obj )

Returns an object's own and inherited property descriptors.

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

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

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

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': {...}, ... }
