What is it

Arguments in Graphql provide a way for other node/entity connections and sub-fields to retain context from the parent node/entity

const resolvers = {
  Query: {
    user(parent, args, contextValue, info) {
      return users.find((user) => user.id === args.id);
    },
  },
};

`parent`

The return value of the resolver for this field's parent (previous resolver in the resolver chain)

For top-level fields with no parent, this value is obtained from the rootValue function passed to Apollo server's constructor

An object that contains all GraphQL arguments provided for this field.

# query
query {
  user(id: "4")
}

# arg passed to user resolver
{ "id": "4" }

Object shared across all resolvers executing for a particular operation.

Use this to share per-operation state

use this for auth information, dataloader instances, and anything else to track across resolvers

When calling a service method on a resolver field, to keep the context, you might have to pass the context explicitly as another parameter

Information aobut the operation's execution state.
