The instructions at "Getting Started With GraphQL.js" are not working

Description

The instructions at the page Getting Started With GraphQL.js didn't work for me.
Even though the page mentions Node v6, I expected that it should work on more recent versions as well.

Steps to Reproduce

Follow the instructions at https://graphql.org/graphql-js/:

1. npm init
2. npm install graphql --save
3. Create the server.js file

var { graphql, buildSchema } = require('graphql');

// Construct a schema, using GraphQL schema language
var schema = buildSchema(`
  type Query {
    hello: String
  }
`);

// The root provides a resolver function for each API endpoint
var root = {
  hello: () => {
    return 'Hello world!';
  },
};

// Run the GraphQL query '{ hello }' and print out the response
graphql(schema, '{ hello }', root).then((response) => {
  console.log(response);
});

4. Run node server.js

Expected Result

{ data: { hello: 'Hello world!' } }

Actual Result

UnhandledPromiseRejectionWarning: Error: Expected undefined to be a GraphQL schema.

Additional Context

The installed package version was "graphql": "^16.0.1".
The node version I used was v14.17.0.

Hey @fskuteken

I've submitted a PR to fix this.

If you update the last part to be the following, it'll work:

graphql({ schema, source: '{ hello }', rootValue: root }).then((response) => {
  console.log(response);
});

This was fixed by #1186 - closing, thanks!
