As a developer I'm interested enough to try React.js on my next project. However, it seems like designers will still need to write Javascript to implement repeating structures (tables, lists, etc.)? Just like designers don't want me fiddling with their HTML and CSS, I don't want them fiddling with my code -- but React.js's model seems to make such a separation of concerns impossible?
You can of course continue to have designers handoff markup/CSS for integration by engineering. But if your designer can handle basic javascript, you needn't involve engineering at all. In practice it doesn't really matter if the individual views are sloppy javascript since React separates concerns so well.
