• [nitpick] The variable name minLength conflicts with the property name being demonstrated. Consider using a more descriptive name like minLengthValidator or minLengthConfig to avoid confusion.

 *     const minLength = [5, 'The value of path `{PATH}` (`{VALUE}`) is shorter than the minimum allowed length ({MINLENGTH}).'];
