/aside Is most adoption of new frameworks due to old developers switching, or new developers entering the market? JS frameworks are the Drosophila of software, which is surely partly due to the accessibility and popularity of JS, its flexibility and flaws, and also of course that the problem frameworks solve gets better understood and then changes, and the solutions improve. But perhaps also, JS developers themselves are the Drosophila of software developers, quickly entering and exiting the JS field. In many fields, new blood drives adoption.
