I meant that React Native can become a replacement for the parts of the web (or just html, the web is bigger) that try to be an application inside what is essentially a document viewer.
I think the web (or rather html) is wonderful for what it was intended for - document viewing and editing (sometimes collaboratively).
Blogs, newspapers, Q&A sites and anything built around content really, should definitely still be in built using html/web , but the various SaaS products should be built using a tool built for apps.
Exactly. Therefore, in my opinion, Facebook should instead try to get the web back on track of being the application delivery standard. If this is not possible (google/apple not cooperating), they should imho give ReactNative an API that is compatible with the web. Of course, they can build their virtual dom etcetera on top of that (but it should be optional).
And as far as I know, FB actually tries hard to improve web by participating TC 39 actively. Web is still big part of them.
