The Complete React Developer Course (with Hooks and Redux) - Dropdown for Picking SortBy

The video tutorial covers how to implement sorting options for data by date and amount using a select dropdown in a React application. It begins by discussing the current sorting method and the need for improvement. The tutorial then enhances test data to validate sorting functionality effectively. It proceeds to set up a select dropdown in JSX, similar to HTML, and explains how to handle changes using event handlers. The concept of controlled inputs in React is introduced, highlighting their advantages in managing form inputs. The tutorial concludes with a demonstration of the implemented features.
