With QT5 and it's qt quick controls 2, I put together the demos of the first few chapters of "Full Stack React" within minutes. The QT creator helped me with this. I compiled to desktop (which is quicker) and then when I was done I compiled to WASM and loaded it up in the browser.<p>With React and other DOM based tools, it takes very long to develop even simple GUI's. There are tools like React Studio, but nothing as mature as QT. Also QML and Signal/Slots are much better than React's model IMHO. In addition, Virtual-DOM is a hack that only DOM based models suffer from and adds overhead to the development model.<p>I think the article is right -- Out with the new, in with the old!
