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

It's important that for all the forms in our application, the styles and the way we notify users of errors need to be consistent. One way to do this is to copy the entire form code and paste it into the different pages where we need a form. But this is bad practice because whenever we want to change anything in the form, we'll need to change it in multiple places. Besides, it's always a bad idea to repeat ourselves, especially when we can avoid it. What we want to do instead is to build a set of reusable form components that we can apply across different forms in an app. 

To get started, we'll create a FormikWrapper component. This is what will house our Formik context provider. This makes it possible for us to add other reusable components to our form, with each of them having access to the form's state wherever they are used.
