Docs are looking great! It might just need a bit more detail

[jedel1043]

Looks good so far, but you only mentioned what the bytecompiler does, not how it does it.

• Is it register based, stack based or other type?
• Does it use a string interner?
• How does it resolve bindings and environments?
• What about async? Does it lower async/generators to state machines or to some other execution model?
• etc.
