In React the DOM API takes a data map in the first position, for Elements the data takes the second position after the type function.

React controls access to the constructed type.

Starting to play around with [React](http://facebook.github.io/react/). I found JSX off-putting at first but the reactive paradigm and virtual DOM are pulling me in.

Playing around with the live JSX compiler is also interesting for understand what the value of the syntax sugar is.

[Flight](https://github.com/flightjs/flight) is interesting in its use of jQuery and the DOM. Rather than taking the VirtualDOM and in-memory approach it seems to be banking on the value of native APIs.
