I'm kind of a hoplon noob, but I've heard about it for the first time probably already 10 years ago. How is performance compared to, say, React?

measured in parentheses per second?

tl;dr
• problem react solves is needing to necessarily empty out all dom nodes before you add them all back, like if you're syncing an array with a set of elements (like an array to a bunch of todo <li>
• hoplon solves differently by promoting fine-grained subscriptions to cells. DOM nodes are pooled and reused, no diffing other than clj = inside javelin

it's basically immediate mode (React) vs. retained mode (Hoplon+Javelin, DOM), in UI speak
