Frequently Asked Questions

How are nested objects handled?

Nested objects generate their own named type definition, referenced from the parent type. This keeps your code organized and reusable.

How are arrays typed?

Arrays infer their element type from the first item. Arrays of objects generate a collection type of the corresponding object type.
