"The Object.defineProperties() method defines new or modifies existing 
properties directly on an object, returning the object."

https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperties

However, in the polyfill 
https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperties#Polyfill

I see:

   if (typeof obj !== 'object' || obj === null)
     throw new TypeError('bad obj');

I think here it should be check for null and all primitive types 
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures

Native built-in Object.defineProperties method allows me to add 
properties to a function as the function is an object.

Am I thinking correctly that mentioned polyfill has a bug?
