How can I use Formik with TypeScript?

You can use Formik with TypeScript by defining your form values and using the Formik component with type annotations.

Can you show me a simple example?

Sure! Here's a basic example:

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

interface MyFormValues {
  name: string;
  email: string;
}

const MyForm = () => {
  const initialValues: MyFormValues = { name: '', email: '' };

  return (
    <Formik initialValues={initialValues} onSubmit={values => console.log(values)}>
      <Form>
        <Field name="name" placeholder="Name" />
        <Field name="email" placeholder="Email" />
        <button type="submit">Submit</button>
      </Form>
    </Formik>
  );
};

This sets up a simple form with name and email fields.

What are the benefits of using Formik with TypeScript?
