The below code registers a field called listOfStrings that returns a list of strings as the result:

add_action( 'graphql_register_types', function() {

	register_graphql_field( 'RootQuery', 'listOfStrings', [
		'type' => [ 'list_of' => 'String' ],
		'resolve' => function() {
			return [
				'String One',
				'String Two'
			];
		}
	] );

} );

This field can now be queried:

{
  listOfStrings
}
