How can I efficiently collect data in a React application?

You can use controlled components to manage form data, or libraries like Formik and React Hook Form for better handling.

What are controlled components?

Controlled components are React components that do not maintain their own state. Instead, they receive their current value from props and notify changes via callbacks.

Can you give me an example of a controlled component?

Sure! Here's a simple example:

function MyInput() {
  const [value, setValue] = useState('');

  return (
    <input
      type="text"
      value={value}
      onChange={(e) => setValue(e.target.value)}
    />
  );
}

What about using libraries like Formik?

Formik simplifies form handling in React by managing form state, validation, and submission, making it easier to build complex forms.
