I gave this tutorial (and React) a shot, since I find the concept of server/client apps intriguing, but stopped reading halfway through the Flux documentation.

I can't decide whether I love or hate React w/ Flux, but the one thing I'm sure of is that the documentation was written by someone who had pain in some framework I haven't had experience with. I've used Knockout extensively in a medium sized web application and reasoning about the source of data updates and dependency invalidation hasn't really been a problem at all. And that's the perfect example of the data-binding and dependency modeling which seems to be what React is eschewing. shrug Either way I'm still intrigued and will give it another go when I have more free time.
