React Native is a framework for building native mobile apps using JavaScript and React. It was created in 2013 and allows building iOS and Android apps with the same code base using a component-based and unidirectional data flow approach. The core team consists of native iOS and Android developers, and it aims to provide a faster development process than building separate apps for each platform from scratch. React Native uses a JavaScript runtime to render UI components to native mobile components without using HTML.

8. “Most of the core React Native team are
actually native iOS and Android developers,
so it's definitely not that we prefer
JavaScript over native code.“

9. “Building and maintaining wholly separate
apps for each platform is hugely inefficient
[...].
And the actual native development process
of write/compile/deploy/debug is also slow
compared the web approach.“

13. “We're not promising to give you One Weird
Trick that allows you to change nothing
about your development
philosophy/practices and yet
automatically create excellent mobile
experiences.“

25. “We already have React Native inside the
Facebook app (on iOS and Android), and
using it for some features. But it's still in the
experimental phase for now, we hope to ship
some bigger.“
