Some error messages which relate to user input should be displayed to the user's in his User Interface, those can be displayed by callback functions on the error occurrence ( for e.g. entering of characters or bypassing mix/max limits ), those can be done by using the callback functions as follows.

new AutoNumeric("#element_id",{
          onErrorCallback: message => { displayErrorMsg(message) },
          onResetErrorCallback: () => { resetErorrMsg() },
});

P.S. I had to delete the previous pull request because the earlier code + pull request was failing on eslint rules, and build was failing on that, i have corrected code accordingly, and now the build succeeds properly.
