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,
);

Here is a example of no parent.

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

console.log(
  Reflect.getPrototypeOf(h) === null,
);
