And yet, QT picked JS for the language of its state of the art widget library. Not to mention a lot of QT apps bundle the entire thing as well, so I have in my PC several versions of qt5win.dll and friends, many exactly the same. Furthermore QT apps are not a guarantee of fast programs, and often the interfaces look horrible. I fail to see a huge difference in programming methods, even if the QT runtime clocks at about 50mb instead of 500mb.
