What are the benefits of using Formik with TypeScript?

Using Formik with TypeScript helps catch errors at compile time, improves code readability, and enhances developer experience.

Can you show me a simple example?

Sure! Here's a basic example:

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

const MyForm = () => (
  <Formik
    initialValues={{ name: '' }}
    onSubmit={values => { console.log(values); }}
  >
    {() => (
      <Form>
        <Field name="name" type="text" />
        <button type="submit">Submit</button>
