8. Add resolvers for the necessary fields on the Comment type
9. Add comment fields to User and Post and add the required resolvers
10. Make some queries for your new types

Part 2

1. Create a new mutation createPost with the required arguments
2. Create a resolver for createPost. Make sure to check that an author exists for the author id argument.
3. If you haven't used an input type, refactor your code to use one.
4. Test your code by creating some users. (Remember, since we are not writing to a database or file, once you refresh the server, the newly created users will have disappeared)
5. Repeat steps 1 to 4 for createComment

Part 3

1. Try subscribing to the post subscription and then creating a new post.
2. Create a subscription comment that takes an argument postId which will notify of a new comment published for a given post. Remember, you can pass any string into the PubSub asyncIterator function, so you can pass the postId in there.
3. Try subscribing to your new comment subscription for one of your posts. Then create a comment for it.
