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

In React, **hooks** are reusable functions that allow us to access the state and lifecycle methods of functional components. We can use them to write **stateful logic** (any logic that depends on the state of the component).

The `useFormik` hook is a custom hook provided by Formik used to initialize and configure a Formik form instance. It accepts an object as an argument and returns an object containing various properties and methods that we can use to manage the state and behavior of the form, hence, making our lives easier.

Let's create a simple form.

# A reservation form

We'll create a form component in our `src/components` folder and import the component into our app.js file. The name of the file will be ReservoForm.js.
