I'm lead to believe that either jquery isn't useful for dealing with virtual DOMs, or that it does screwy things when working together with a virtual DOM system (like react) or both. I've also heard claims that React's theory of slow DOMs is wrong. Which doesn't make it a 'bad' framework to make use of, just optimized on the wrong thing. I haven't had time to suss this out. I spend a lot of time in "good enough for now" mode because I'm not a dedicated front-end person.
