How can I implement feedback validation in my React app?

You can use controlled components along with validation libraries like Formik or Yup to handle feedback validation.

Can you show me a simple example using Formik?

Sure! Here's a basic example:

import { Formik, Form, Field, ErrorMessage } from 'formik';

const FeedbackForm = () => {
  return (
    <Formik
      initialValues={{ feedback: '' }}
      validate={values => {
        const errors = {};
        if (!values.feedback) {
          errors.feedback = 'Required';
        }
        return errors;
      }}
      onSubmit={(values, { setSubmitting }) => {
        console.log('Feedback submitted:', values);
        setSubmitting(false);
      }}
    >
      {({ isSubmitting }) => (
        <Form>
          <Field type="text" name="feedback" />
          <ErrorMessage name="feedback" component="div" />
          <button type="submit" disabled={isSubmitting}>Submit</button>
        </Form>
      )}
    </Formik>
  );
};

This will validate that the feedback field is not empty.

What if I want to add more fields to the form?

You can easily add more fields by including additional <Field> components and updating the initialValues and validate functions accordingly.
