Curiously, I would say that if a frontend technology is fast then that's already improved the user-experience. If your user can click around quickly and if making a mistake isn't a huge setback in terms of time to navigate through loading screens etc. It also gives developers a good starting point - no need to optimise if the language is just natively snappy.
