JavaScript: Reflect.getPrototypeOf

New in JS2015.

Reflect.getPrototypeOf(obj)

Return the parent object. Return null if no parent. Throw a TypeError exception if obj is not a object.

console.log( 
 Reflect.getPrototypeOf ( {} ) === Object.prototype
); // true

Here is a example of no parent.

// create a object with no parent
const h = Object.create( null);

console.log( 
 Reflect.getPrototypeOf ( h ) === null
); // true

Reflect.getPrototypeOf vs Object.getPrototypeOf

Object.getPrototypeOf(obj) will convert obj to a object first.
