> In case of microcontrollers, PXT programs are compiled in the browser to ARM Thumb assembly, and then to machine code, resulting in a file which is then deployed to the microcontroller, usually via USB mass-storage interface.

Maybe my memory is fuzzy about the exact workflow, in any case you can check "Microsoft MakeCode: from C++ to TypeScript and Blockly (and Back)" https://www.youtube.com/watch?v=tGhhV2kfJ-w https://www.youtube.com/watch?v=tGhhV2kfJ-w and the respective C++ FFI, https://makecode.com/simshim https://makecode.com/simshim
