MapStateToProps is a function provided by React Redux so we can map the state directly to the props of our component, as the function name suggests. The modal will be defined on the home page. When saving is successful we set the contacts in the store and call onSaveprop, which is a function to close the modal that the form is in. The handleSubmit function checks if the data is valid and if it is, it will proceed to save according to whether it is adding or editing a contact. The parameter of the ContactForm function are props, which we will pass in from the HomePage component that we will build later. The second argument of the matches, min, and max functions are also validation messages. The argument in the required function is the validation error message. The schema object is what Formik will check against for form validation. To display form validation messages, we have to pass in the isInvalid prop to each Form.Control component. Notice that, in each value prop, we have ||'' so we do not get undefined values and prevent uncontrolled form warnings from getting triggered. The parameter in the function is the data we entered, with the field name as the key, as defined by the name attribute of each field and the value of each field as the value of those keys. handleSubmit is the function that we passed into the onSubmit handler of the Formik component. HandleChange is a function that lets us update the form field data from the inputs without writing the code ourselves.
