JavaScript: How many objects are allocated when returning an object literal from a class constructor?

Let's say I have this code:

class MyClass { constructor() { return {}; } } const x = new MyClass(); // how many objects are instantiated with this?

I know that variable x just holds a reference to the empty object literal {} returned from the constructor. But, for the purposes of knowing what is actually allocated behind the scenes in JavaScript, does JavaScript instantiate two objects, and instantly throw one away?
