Yes, all of those don't really matter. You just fire up whatever and start building the damn thing.

well in this case I think it does.. Animating this many DOM elements in a performant way would be really hard. Looks like the webapp is rendered in a <canvas/> element. I think its a better discussion than 'which js framework should I use?'

Thanks for your interest. Performance has been har to get good enough. Basically it is a javascript app on a canvas. Thats why it can be integrated on the landing page.

You seem to have accidentally invented a really slick UI library for canvas. I have been working off and on on something like that for the last 3 years, but yours is actually factually working. I really hope you publish it.

Interesting. Do you repaint the entire canvas on every update?
