React Form Library is a tool used by web developers to make it easier to create and manage forms in their React applications. Forms are an important part of many websites, allowing users to input and submit data. However, handling form inputs, validation, and submission can be complex and time-consuming. The React Form Library simplifies this process by providing pre-built components and functions that handle common form tasks. It helps developers manage the state of form inputs, validate user input, and handle form submission with ease. This library makes it more efficient for web developers to build interactive and user-friendly forms in their React projects.

npm install react-hook-form
import { useForm } from 'react-hook-form';
function App() {
const {
register,
handleSubmit,
formState: { errors },
} = useForm();
return (
<form onSubmit={handleSubmit((data) => console.log(data))}>
<input {...register('firstName')} />
<input {...register('lastName', { required: true })} />
{errors.lastName && <p>Last name is required.</p>}
<input {...register('age', { pattern: /\d+/ })} />
{errors.age && <p>Please enter number for age.</p>}
<input type="submit" />
</form>
);
