GraphQL - Resolvers

You want to fetch a list of books published after year 2000 using a GraphQL query with an argument publishedAfter. Which query correctly uses the args to achieve this?

A{ books["publishedAfter": 2000] { title author } }

B{ books { title author publishedAfter: 2000 } }

C{ books(publishedAfter: 2000) { title author } }

D{ books(publishedAfter = 2000) { title author } }

Step-by-Step Solution

Solution:

Step 1: Understand how to pass args in GraphQL
Arguments must be inside parentheses after the field name, using colon to assign values.
Step 2: Evaluate each option
{ books(publishedAfter: 2000) { title author } } correctly uses parentheses and colon. { books { title author publishedAfter: 2000 } } places argument inside selection set which is invalid. { books(publishedAfter = 2000) { title author } } uses equals sign instead of colon. { books["publishedAfter": 2000] { title author } } uses brackets and quotes incorrectly.
Final Answer:
{ books(publishedAfter: 2000) { title author } } -> Option C
Quick Check:
Args inside parentheses with colon [OK]

Quick Trick: Args go inside parentheses with colon [OK]

Common Mistakes:
