Answer 1

According to its 2019 edition, React is currently more often used by developers than Angular (31.3% vs 30.7%). Additionally, React is more loved (74.5% vs 57.6%) as well as more wanted (21.5% vs 12.2%) technology among the developers. Finally, what may be interesting especially for Google, is the fact that Angular is one of the most dreaded technologies on the market (42.6% vs 25.5%). This can be an effect of a few things, including the fact that Angular is more complicated than React (especially for newcomers) due to its use of TypeScript.
It’s also worth noting that React ended up with better results in the 2019 survey than in the 2018 one. Back then, Angular was slightly more popular among developers (36,9% vs React’s 27,8%), and React became even more loved and wanted throughout these past 12 months.
