}

const input = { name: "???" };

const [data, errors] = validate(input, CoolValidator, (value) => ({

};

// Do not validate empty fields (validation only)
const dryRun = true;

const [data, errors] = validate(input, (value) => ({
  given_name: value("givenName")
    .notEmpty({ if: !dryRun })
    .isLength({ min: 3, max: 25 }),
