/**
 * Builds a schema from the provided type definitions and resolvers.
 *
 * The type definitions are written using Schema Definition Language (SDL). They
 * can be provided as a string, a `DocumentNode`, a function, or an array of any
 * of these. If a function is provided, it will be passed no arguments and
 * should return an array of strings or `DocumentNode`s.
 *
 * Note: You can use GraphQL magic comment provide additional syntax
 * highlighting in your editor (with the appropriate editor plugin).
 *
 * ```js
 * const typeDefs = /* GraphQL *\/ `
 *   type Query {
 *     posts: [Post]
 *     author(id: Int!): Author
 *   }
 * `;
 * ```
 *
 * The `resolvers` object should be a map of type names to nested object, which
 * themselves map the type's fields to their appropriate resolvers.
 * See the [Resolvers](/docs/resolvers) section of the documentation for more details.
 *
 * ```js
 * const resolvers = {
 *   Query: {
 *     posts: (obj, args, ctx, info) => getAllPosts(),
 *     author: (obj, args, ctx, info) => getAuthorById(args.id)
 *   }
 * };
 * ```
 *
 * Once you've defined both the `typeDefs` and `resolvers`, you can create your
 * schema:
 *
 * ```js
 * const schema = makeExecutableSchema({
 *   typeDefs,
 *   resolvers,
 * })
 * ```
