Sık sorulan sorular

How are arrays typed?

Element types are inferred and merged: a mixed [1, 'a'] becomes Array<number | string>.

Interface vs type?

Interfaces are extensible via declaration merging; types are more flexible with unions and mapped types. Toggle in the UI to switch.

What about optional fields?

Only the fields present in your sample are emitted. Merge multiple samples with a union type if some fields are conditionally present.
