 * export default defineConfig({

 * type of this function.
 *
 * @param config Your config. See {@link https://hardhat.org/config}.
 * @returns The config.

    // Why does it exist?
    //  - It gives autocomplete of the config both to js and ts users.
    //  - It allows you to define and export the config in a single statement,
    //    having type-safety without much more verbosity.
    //  - While it doesn't do anything, it feels mandatory, so most users will
    //    use it and have a better user experience.
