Are nested objects turned into separate structs?

Yes, each nested object generates its own named struct based on the field name.

How are arrays typed?

Arrays become Go slices, e.g. []string or []int, based on their first element.

What if a field is null?

Null fields are typed as interface{} since no concrete type can be inferred.
