What is React Hook Form and how do I use it?

React Hook Form is a library for managing forms in React applications. It simplifies form validation and state management.

Can you show me a basic example of how to implement it?

Sure! First, install it using npm: npm install react-hook-form. Then, you can create a simple form like this:

import { useForm } from 'react-hook-form';

function MyForm() {
  const { register, handleSubmit } = useForm();
  const onSubmit = data => console.log(data);

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input {...register('example')} />
      <input type="submit" />
    </form>
  );
}

How do I add validation to the form fields?

You can add validation by passing rules to the register function. For example:

<input {...register('example', { required: true })} />

This will make the field required.
