@ -53,7 +53,7 @@ The resolver parameters generally follow this naming convention and are describe
1. `parent`: The object that contains the result returned from the resolver on the parent field, or, in the case of a top-level `Query` field, the `rootValue` passed from the [server configuration](./server.html). This argument enables the nested nature of GraphQL queries.
2. `args`: An object with the arguments passed into the field in the query. For example, if the field was called with `query{ key(arg: "you meant") }`, the `args` object would be: `{ "arg": "you meant" }`.
3. `context`: This is an object shared by all resolvers in a particular query, and is used to contain per-request state, including authentication information, dataloader instances, and anything else that should be taken into account when resolving the query. Read [this section](#context) for an explanation of when and how to use context.
4. `info`: This argument contains information about the execution state of the query, including the field name, path to the field from the root, and more. It's only documented in the [GraphQL.js source code](https://github.com/graphql/graphql-js/blob/c82ff68f52722c20f10da69c9e50a030a1f218ae/src/type/definition.js#L489-L500), but is extended with additional functionality by other modules, like [`apollo-cache-control`](https://github.com/apollographql/apollo-cache-control-js).

In addition to returning GraphQL defined [scalars](./schema.html#scalar), you can return [custom scalars](../features/scalars-enums.html) for special use cases, such as JSON or big integers.
