What is the args argument in a GraphQL resolver?

The args object (second resolver argument) contains all the arguments passed to the field in the query. Arguments are defined in the schema: user(id: ID!): User. In the resolver: Query: { user: (parent, args, context) => db.user.findById(args.id) }. Arguments can be scalars, enums, or input types. For a mutation: createUser(input: CreateUserInput!): User → resolver receives args.input.name, args.input.email. Arguments are validated by GraphQL before reaching the resolver — if a required argument is missing or the wrong type, execution fails before the resolver is called. Default values in schema: field(limit: Int = 10). Args are useful for filtering, pagination, IDs, and any operation parameter.
