Interface Type Definition
When a field can return one of a heterogeneous set of types, a Interface type is used to describe what types are possible, what fields are in common across all types, as well as a function to determine which type is actually used when the field is resolved.
Example:
const EntityType = new GraphQLInterfaceType({
name: 'Entity',
fields: {
name: { type: GraphQLString }
}
});
