Clearing all elements from a Set in JavaScript is essential when you need to reset a collection while maintaining the same Set instance for continued use. As the creator of CoreUI with 25 years of JavaScript experience since 2000, I’ve used Set clearing operations extensively in data management systems and user interface state management. The most efficient approach uses the built-in clear() method which removes all elements from a Set in a single operation. This method provides optimal performance while maintaining clean, readable code for collection management.

Using methods is fundamental for organizing component logic in Vue applications, providing a clean way to handle events and execute reusable functions. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented thousands of Vue methods across components for form handling, data manipulation, and user interactions in enterprise applications. From my expertise, the most effective approach is to define methods in the methods option with proper naming conventions. This method provides clear component organization, automatic this binding, and excellent debugging experience.
