First Impressions Using React Native

The "declarative component model" is not an innovation, it's an obvious approach that has been used for ages when prototyping. You can achieve the same conceptual model of your interface by just generating the entire HTML of the page and rerendering it whenever something changes. This obviously doesn't perform and has some edge cases where it breaks things (textboxes, for example), but the idea is the same as react's components.

FRP is based around the idea of declarative components, but a lot of developers have an aversion to it because of the academic aura around it.

React's innovation is using virtual DOM to make declarative components usable without delving into FRP.

Not just that. I may be stupid but personally I find it mentally simpler to `setState` than to `flatMapLatest`. To each their own I suppose.

Precisely.

React is not an academic paper, it's a tool. It doesn't need to have new ideas, it needs to execute on them in a practical way. Which it does.
