There's no particular commit I can point to and say that I'm most proud of this thing. I think that a lot of open source work is about grinding away together at a big problem -- fixing bugs here and there, adding a feature that you need, updating some documentation that you saw was missing. There's also a story beyond the commits themselves -- @ide and I have spent countless hours helping people on issues, discussing React Native with people at Facebook and in the community and pushing forward various initiatives to improve it, in particular to make it more powerful without forcing you to drop down to native code.
