Here is my version of abstractfactory.

Look at the text I wrote at the top of index.ts and explodingroom.ts . You may find that helpful.

In explodingroom.ts, I added a second implementation of the factory: one built "from scratch", and one built by inheritance. I put some explanation about the relationship between AbstractFactory and the use of inheritance to build new factories. See if you like it.

I was unable to standardize on "export default" because (a) I couldn't figure out the syntax for exporting more than one value from a file and (b) when I tried to export an interface, TS complained that it was not possible to export a type.

I also got a nasty type error which turned out to be because I was importing one thing from a file, and the default export was something else.

So the code standardizes on locally declaring exports, and then importing

import {Foo, Bar} from './whatever'

I suspect that the True TypeScript way is to say

import * as what from './whatever/
and then writing
what.Foo and what.Bar

But I don't assert that with much confidence.

Enjoy!
