Function Operation
The Function operation executes JavaScript/TypeScript code synchronously via the Function Service. Functions return results directly and are ideal for custom business logic that cannot be expressed in GraphQL, data transformations, integration with external APIs, and complex calculations.
For more details on writing functions, refer to the Function Service documentation.
