forum.makecode.com/t/help-understanding-local-build-options/6130 asks how to compile locally and suggests it is possible. Seems to require Yotta, so presumably compiles?
Presumably this is because Microsoft ported their MakeCode thing to the MicroBit, and the Micro Bit foundation accepted them.
E.g. there toggling a LED:
but the code that works locally is a completely differently named API
Microsoft going all in on adopt extend extinguish from an early age!
