GraphQL - Resolvers

Given the schema:

type Query { user: User }

and resolvers:

Query: { user: () => ({ id: 1, name: 'Alice' }) }, User: { name: (parent) => parent.name.toUpperCase() }

What will be the result of the query { user { name } }?

A{ "user": { "name": null } }

B{ "user": { "name": "Alice" } }

C{ "user": { "name": "ALICE" } }

DError: Cannot read property 'toUpperCase' of undefined

Step-by-Step Solution

Solution:

Step 1: Understand root resolver output
The root Query resolver returns an object with id and name fields.
Step 2: Analyze User resolver for name
The User resolver for name receives the parent object and calls toUpperCase() on parent.name, converting 'Alice' to 'ALICE'.
Final Answer:
{ "user": { "name": "ALICE" } } -> Option C
Quick Check:
Parent.name uppercased = ALICE [OK]

Quick Trick: Parent holds user object; use it to transform fields [OK]

Common Mistakes:

Forgetting to use parent argument
Assuming name is unchanged
Expecting null or error
