class-extend | Backbone like Class.extend for Node.js | Runtime Evironment library

My problem is very close to this one: Typescript: instance of an abstract class but it's also slightly different. If it's truly a duplicate, I would like a reasonable explanation at least because I do not know how to solve this problem.

I've got a Base class:

I have two Class variables, one obtained from looping the keys of a HashMap, we'll call it A, and one passed as a parameter, which we'll call B. I'd like to see if B extends A.

So, as I currently understand things, I'd make an instance of B (using createInstance) and check instanceof. But this is not only pretty slow, but cumbersome as classes need an empty constructor. See here and here, where they discuss isAssignableFrom and getSuperClass, but isAssignableFrom (from what I read there) doesn't work on the same class (SomeClass.isAssignableFrom(SomeClass) ?), and getSuperClass doesn't walk up the tree.

Is there a way I can check if B extends A without creating an instance of B?

For example:

I’m trying to create dependency injection of my ViewModel using Dagger2 with multi binds but I’m receiving this error and I can’t make it work, I tried several answers (below) but none of them helped me.

This is the error I receive :

First of all, ive read this question React-redux connect() cannot wrap component defined as a class extending React.Component But im still unable to uderstand it since the connect is being done in some kind of upper level, but I dont understand that phase.

This is my current structure:

reduxStore.js

When answering this question: Typescript: class extending Array, can't assign method where the original author extended Array class to add some methods, I arrived to following class:
