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

Sometimes, we might want to collect a value multiple times, but prior to collecting the values we don't know the exact number of times we want to collect them. For example, if we ask our users to enter the names of their friends, we may not know how many friends they have, so we want to give them the flexibility to add and remove as many friends as they would like. We'll save all the values in a single array. This requires us to do a lot of array manipulation that can quickly get complex. Formik provides a component that helps us easily manipulate arrays—the `FieldArray` component.

Learn how to use the FieldArray component to do common array manipulations on a form's state.
