At the very least it proves you don't need OOP to do UIs. It is more difficult to implement ECS (there isn't a long tradition of it and libraries like MVC has)

At the very least it proves you don't need OOP to do UIs. It is more difficult to implement ECS (there isn't a long tradition of it and libraries like MVC has) but well worth the effort. It's more suited to native UIs than webapps though.
