You can do that with Github Pages, but I'm not too knowledgable. But I copied your code in an codesandbox:

Fork it if you want, I will delete it then (or on your request)

You can leave it if you wish. I'll have to learn a bit more about https://codesandbox.io/, it looks very useful.

Apparently the contents of the page were somehow mangled a bit. As a result it is not functional.

I ended up looking into Github Pages and it wasn't too hard to use. (The documentation makes it look harder that it actually is.)

Thank you, benjaminsuch, for that pointer.
