Convert to ES6 Classes

The video tutorial demonstrates how to convert an ES5 object-oriented application using prototypes into an ES6 class-based application. It begins by explaining the transition from ES5 to ES6, then defines two classes, Book and UI, with constructors. The UI class is expanded with methods for user interaction, such as adding books, showing alerts, deleting books, and clearing fields. Event listeners and validation processes are set up, and the application is tested to ensure functionality. The tutorial concludes by highlighting the syntactical improvements of ES6 classes over ES5.
