Perhaps unsuprisingly, React's own web site is a great example of how to do React right. By the looks of it it's not loading the entire page into Virtual DOM, it's got code splitting, loading on demand... all the absolutely right things. A lot of React sites I see in the wild have none of this. They have a multi-MB JS blob that gets downloaded immediately on load and parses a giant JSON blob stored in the HTML that represents the page state. I'm not saying React isn't useful or that it can't be done well. I'm saying that in a lot of cases it just isn't done well. Whether that's down to a lack of education or a lack of care I don't know.
