Make a React Form Component that Handles Inserts and Updates

The term "upsert" means to support both inserting a new record and update an existing record. In order to support upsert capabilities with a form in React, we need to determine which mode we're in and if we're performing an update, we need to make sure the form fields are populated the existing values for the item being updated. In this lesson, we'll refactor an exiting form to handle updates and verify that we've also maintained the ability to use that same form component to insert new records.
