JS: Reflect.getPrototypeOf

(new in ECMAScript 2015)

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);

Here is a example of no parent.

console.log(Reflect.getPrototypeOf(Object.create(null)) === null);
