It's not all that much different than html or even React. You can assign each part to named functions and turn it into something more like this:

    LandingPageDesktop(landingPageDesktopId, landingPageDesktopProperties) {
      LandingPage(landingPageId, landingPageProperties) {
        LeftText() {
          etc...
        }
      }
    }

The real issue is trying to represent graphical objects, and the relationship between those objects, with text. Graphical builders/RAD tools seem like such an obvious solution, but that approach has largely been abandoned.
