* The leaf values of any request and input values to arguments are

*
* If a type's serialize function returns `null` or does not return a value
* (i.e. it returns `undefined`) then an error will be raised and a `null`
* value will be returned in the response. It is always better to validate
*
* Example:
*
* ```ts
* const OddType = new GraphQLScalarType({
* name: 'Odd',
* serialize(value) {
* if (!Number.isFinite(value)) {
* throw new Error(
* `Scalar "Odd" cannot represent "${value}" since it is not a finite number.`,

* const AddressType = new GraphQLObjectType({

* });
* ```
*
* When two types need to refer to each other, or a type needs to refer to
* itself in a field, you can use a function expression (aka a closure or a
* thunk) to supply the fields lazily.
*
* Example:
*
* ```ts
* const PersonType = new GraphQLObjectType({
* name: 'Person',
* fields: () => ({
* name: { type: GraphQLString },
* bestFriend: { type: PersonType },
* })

* Use a unique identifier name for your extension, for example the name of
* your library or project. Do not use a shortened identifier as this increases
* the risk of conflicts. We recommend you add at most one extension field,
* an object which can contain all the values you need.
