it is quite easy to maintain a large, flexible, well-engineered SPA with React, Vue, or other lightweight JS libraries, even at enterprise companies with large teams.
Vue's initial release was just over three years ago. Other technologies used by enterprise companies has usually proven itself for a decade or two. Articles like this don't help with JavaScript fatigue.
