Make Code looks like a better option: https://minecraft.makecode.com/
These presentations from Microsoft Build conference look great but I still hadn't time to watch:
Make Code with Blocks https://mybuild.microsoft.com/sessions/3d1f48b8-54de-4af4-a4...
Make Code with Python https://mybuild.microsoft.com/sessions/256b9486-d200-4ed6-99...
The greatest problem with these resources is that they use the XBox Microsoft version, instead of the Java. Maybe this Mod book will be the best thing.
