Modern JavaScript from the Beginning - Second Edition - Modal Component

The video tutorial introduces the concept of modals and UI components, demonstrating how to implement a basic modal with event listeners in JavaScript. It covers the process of opening and closing the modal, and then refactors the code using classes for cleaner and more organized code. The tutorial concludes with an introduction to creating a form component, setting the stage for further development in the next video.
