Google mentioned that all js files rendered but in real, I've lost my title and another meta tags which had been provided by Reactjs on this website and actually lost my position on Google! I've searched a lot but it seems that all pages must have pre-rendered or using SSR(Server Side Rendering) to have their SEO-friendly protocole!
It expands to Reactjs, Angularjs , etc.
For short, Every page that has view page source on browser is indexed by all robots, if it's not probably Google can index but others skip indexing!
