> Web you can get started "instantly". Your browser covers most of the tooling you need and you can tweak any live site.

Obviously you can splat some HTML into a browser and get instant results, but once you start talking about apps with even moderate amounts of interaction, the simplicity of web apps falls away quickly. If you are talking about a sophisticated app, I don't think the complexity is any less when you are using javascript/ React versus Swift/ UIKit. The big win I've seen for javascript/ web apps is the fact that you are reasonably platform independent, obviously if you use Chrome and Chrome specific APIs, that falls away too.
