Great article. The fact that Angular, the framework built by the company who also builds the world's most popular browser, does not have a virtual DOM, is very telling.
I wouldn't acclaim angular for the performance either.
Building apps on it show consistent subpar performance.
generally speaking, Angular handles dom manipulation better than React and Vue. Angular has managed to simplify its enterprise/production applicability and performance is a first-order feature that's hard to f up. React -- you can f performance up before you're done writing your first component.
It's actually a terrible article that has no relevance in 2022, and it is even misleading for 2018 standards.
