That's exactly what I was thinking, too, when reading:

  > I know, it sounds like one of these “duh! moments”, but I can’t think of an instance where I saw this pattern explained in some article. 

The comment section was pretty quick to point out the article that the author couldn't find. I mean, some readers are pushing back because they legitimately disagree, but I was more so confused because React already does this. And it's somewhat well documented. Though the author coming to a similar conclusion by himself is praise worthy.
