/**
* Returns an array of an object's own enumerable and non-enumerable property names.
*
* ## Notes
*
* -   In contrast to the built-in `Object.getOwnPropertyNames()`, this function returns an empty array if provided `undefined` or `null`, rather than throwing an error.
* -   In environments lacking support for `Object.getOwnPropertyNames()`, property descriptors are unavailable, and thus all properties can be safely assumed to be enumerable. Hence, we can defer to calling `Object.keys`, which retrieves all own enumerable property names.
*
* @private
* @param {*} value - input object
* @returns {Array} a list of own property names
*
* @example
* var obj = {
*     'beep': 'boop',
*     'foo': 3.14
* };
*
* var keys = getOwnPropertyNames( obj );
* // e.g., returns [ 'beep', 'foo' ]
*/

	return keys( Object( value ) );
