What are some advanced queries I can use in GraphQL?

In GraphQL, advanced queries can include features like fragments, variables, and nested queries. Would you like examples?

Yes, please provide an example of a nested query.

Sure! Here's an example: you can query a user and their posts like this:

query {
  user(id: "1") {
    name
    posts {
      title
      comments {
        text
      }
    }
  }
}

That looks great! How do I use variables in a query?

You can use variables by defining them in your query. For example:

query getUser($id: ID!) {
  user(id: $id) {
    name
  }
}

Then, you pass the variable value when executing the query.
