javascript - GraphQL query structure

Question

I'm learning GraphQL and am working with Apollo (client and server) I still have some confusion with the structure of GraphQL queries.

Questions:

1. Is it possible to merge the lines labeled #1 and #2 together? As the lines are so similar it almost feels redundant to have both.
2. If it is possible, is it advisable?
3. If not, what is the benefit of having a query structured in this way?

const AddUserQuery = gql`
  /*#1*/mutation addUser($firstName: String!, $lastName: String!, $email: String!) {
    /*#2*/addUser(firstName: $firstName, lastName: $lastName, email: $email) {
      id,
      firstName,
      lastName,
      email
    }
  }`;
...
const [addUser, {data}] = useMutation(AddUserQuery);

Thanks in advance,

不。基本上#1是你，告诉 Apollo 你想要一个突变，这取决于你是否命名它，然后，在 中#2，你告诉 Apollo，你想使用哪个突变。
