couldn't agree more with @realharo. IMHO C++ step learning curve is a no-go for product dev.

what's the problem? If it's a generic error message that's s server-side issue unrelated to RN the team is working on fixing.

I've only seen such thing on infinite non-optimized listviews on old Android crappy phones, but, new listview infra that solves this is coming up soon :)

Although the Instagram website is a React App we are not reusing any code atm. This is something I personally want to explore at some point though.

Great Q. React and React Native use difference "renderers". I believe that with the right pattern to use a different set of low level components you could manage to reuse a big chunk, but this isn't something we have tried so I'm not that sure.

Brace yourself, FlatList is coming :)

No, we didn't use any of those. For unit testing we used Jest <3 and for e2e an internal library developed by FB

Great question. First off, worth mentioning there are many performance metrics you might want to measure. On one hand start up times, but since you specifically mentioned Save, I assume you want to learn more about scroll perf (i.e.: dropped frames, memory usage, time to render next pages, etc).
We don't have numbers we can share but but the React Native team is working on further improving this. Check out Spencer's commit (https://github.com/facebook/react-native/commit/a3457486e39d...) for a sneak peek of what's coming up :).

Oops, that was an internal link - fixing now.

No plans for powering camera using React Native for now. We already have great native infra for that and regardless, IMHO RN might not be the best technology to implement those kind of immersive ultra-performant flows.
We see space for React Native to grow inside of Instagram on flows similar to the ones mentioned on the blog post.

@martinbigio here in case anyone has questions
We also use yarn, an npm client FB built from the ground up to removes some of the pain with npm's one: https://code.facebook.com/posts/1840075619545360
