Keynote - Introducing React Native
summary
React originates inside Facebook's ads org to stop unpredictable cascading updates and replaces imperative mutation with a declarative component model. The demo claims: the virtual DOM diffs make rerendering efficient, the ads create flow stops breaking and development speeds up, and a Groups app using react native ships to the App Store with fully native scrolling and gestures while JavaScript runs off the main thread. Open sourcing in 2013 spreads the ideas; the goal is learn once not write-once-run-anywhere.
