function App() {
  const { register, handleSubmit, errors } = useForm(); // initialise the hook
  const onSubmit = data => {
    console.log(data);
  }; // callback when validation pass

  return (

      <input name="firstname" ref={register} /> {/* register an input */}
      
      <input name="lastname" ref={register({ required: true })} />
      {errors.lastname && 'Last name is required.'}
