Yeah; I think your timeline is off. I don't remember React being the very clear choice until probably 2017. It was still up in the air in 2016, and certainly moreso in 2015.
> by 2015 React "won" the framework battle.
Things have calmed down now. Its better, and has been for a couple years (not 5+ years). But, this isn't a battle. Its not a war. Just because things are calm now, doesn't mean they won't go crazy again.
The core of the issue has nothing to do with technology, or the frameworks, or programming languages. It has everything to do with how you, I, and Dave, who's reading this right now, respond when these new technologies come out. Just. Say. No. Play with them. Build toy projects. Give feedback. But for the love of God, at the end of the day, you Say No. No, we will not be integrating this. Looks cool though, we'll circle back in a year and see what progress you've made.
