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

# What is a multi-step form?
A multi-step form is a long form that is divided into multiple pieces. This makes the form less intimidating to fill and improves the user experience by allowing users to enter information in small chunks.


# Why use multi-step forms?
Forms that request a lot of information often benefit from being broken down into multiple steps. Some of these benefits include the following:

- It makes the user more willing to fill out the form as opposed to when all the form queries are on the same page.

- It opens up the possibility for us to store supplied information in some storage (e.g, local storage) when the user navigates to the next page. This way, if the user refreshes the page, they don't have to start filling out the form afresh.

- Multi-step forms also make the interface more appealing by removing the clogging that long single-step forms could cause.


# How to create a multi-step form
In this section, we'll create a multi-step form that we'll divide into three steps---personal, location, and contact.  


In every step except the last, we'll add a button that helps navigate to the next step, and in every step except the first step, we'll add a button that helps navigate to the previous step. Then, in the last step, we'll include a button to submit the form. 

In each step, there will be a component that shows us all the steps in the form and tells us the current step we are in. It will also let us know the steps we have completed and the ones we are yet to complete. 

In addition, we'll add validation to each step using the `Yup` library. This way the form values for each step have to be valid before the user can move on to the next step or before they can submit the form.

Before we go ahead, well first create a single-step form. Then, we'll convert it into a multi-step form.
