This course focuses on Formik, a JavaScript library for building forms in React. The ability to handle form data is crucial in modern web development, and Formik simplifies the process by allowing you to create forms with less code. You'll learn how to leverage Formik to create complex and straightforward forms with ease.

You'll start with the basics of Formik and gradually work your way up to more advanced topics. You'll learn how to create form fields, handle validation, manage form states, and submit forms. You'll also learn how to use Formik with other popular libraries like Yup for more advanced validation scenarios. 

By the end of this course, you'll be able to create robust and scalable forms in React using Formik. You'll have a deep understanding of how to manage form states, handle form submissions, and validate user input. Data collection is a key element in information technology and will enable you to build better, more organized forms with less code.

Writing React Forms Like a Pro with Formik

While the input field allows us to enter the text, we can only enter the text on one line. So whenever we want our users to enter multiline texts, like descriptions or comments, our best bet is to use the `textarea` field. The `textarea` will have more height than an input field so the user knows that they can enter multiline texts. 

In general, creating a reusable `Textarea` component is done the same way as creating a reusable input field component. One difference is that when we use the `Field` component, we have to pass an `as` prop with a value of `"textarea"`. And if we are not using the `Field` component, we have to use the `textarea` HTML tag instead of the `input` tag.
