My point is that web development is a lot more of a moving target than iOS Native Development and it's largely because Apple makes the hardware, the software, the development tools and the languages and frameworks and they all work together. There are open source libraries in there (SQLite for the default data persistence layer) but it's all vetted and works.
I've been a web developer before (all the way back to and before the ExtJS days) and while I _can_ do it I really prefer not to. The web does not have "the best tooling out of any platform" or "the best documentation... because it's the biggest platform". The tooling tends to be all over the place (until Visual Studio Code takes over the planet... :/) and frameworks like React or Vue hide a lot of complexity that you have to dig into if something goes blooey. This is not to mention the page bloat or security holes you get when you include some handful of analytics "libraries".
