Dart compiles to machine code plus the rendering is mostly impl’d in Dart so you can change basic things about the rendering in Dart, FWIW. In general the dichotomy you’re painting b/w scripting and native languages can hold, but the details make the difference. One interesting thing in this case is having a single language that AOTs but also JITs. The hard thing is re: interfacing to platform APIs, which the OS usually provides in its blessed lang (Java / Obj-C).
