Now you're just being a pedant. Why argue with me about the differenc between 6 days and 2 days? Why have this ludicrous accusation that the other guy definitely doesn't have a good mental model of react and you definitely do? Your entire argument is hinged on calling out the guy for claiming he thinks react was pretty easy to pick up. Why are you arguing with me then when I'm saying it's possible if your position is that it's also possible too if not "plausible." Although I really don't take much weight in your assesment at this point. I tried to give my two cents on the scenario in which I see people pick up react quickly while you're busy calling out this random dude for it not being plausible. Again, it's pretentious. You're not an authority, I have 4 times the experience with react professionally with 2yrs as technical manager and training react devs. I know wtf I'm talking about. There are plenty of people who can learn it in a week whilst you're talking about [ok not years but suggesting that he won't have it down and it takes longer to get a model] and a few I've seen do it quicker. I think you're mixing up actual Dev experience with understanding a UI framework.
