What are custom form hooks in React?

Custom form hooks are reusable functions that manage form state and behavior in React applications.

How do I create a custom form hook?

To create a custom form hook, define a function that uses React's useState and useEffect hooks to manage form data.

Can you give me an example of a custom form hook?

Sure! Here's a simple example:

import { useState } from 'react';

function useForm(initialValues) {
    const [values, setValues] = useState(initialValues);

    const handleChange = (e) => {
        setValues({ ...values, [e.target.name]: e.target.value });
    };

    return [values, handleChange];
}

This hook manages form values and updates them on change.

How can I validate the form data using this hook?

You can add a validation function inside your custom hook and call it before updating the state to ensure data integrity.
