I always wonder where is the VB6/Windows Forms for web apps. I don't want to know the intricacies of Rect/Angular/Vue, I just want to do a declaration of the UI, not programming. Zillions of apps doing the same thing and spending weeks and months on the same problems. I start to think that this is not interesting for, for example, Microsoft because the developer market will shrink and their developers, developers, developers mantra. I remember when Bootstrap come up and suddenly we don't need a lot of graphic design time to build a web page.

Just an additional note about VB6/Windows Forms. They helped to build commodity UIs but when you needed more advanced one you should rely on specific components.
