In GraphQL, directives are special annotations used to modify the behavior of queries, mutations, or the schema itself. They allow developers to conditionally include or exclude fields, modify query execution, or customize schema behavior. Directives increase flexibility and make GraphQL more dynamic by enabling control over how data is fetched, returned, or validated.
Built-in Directives:
- @include(if: Boolean) : Used to conditionally include a field or fragment based on a boolean value.
 - @skip(if: Boolean): Used to conditionally exclude a field or fragment based on a boolean value.
