Creating new HTML elements dynamically is fundamental for building interactive web applications that generate content based on user actions and data. As the creator of CoreUI with over 25 years of JavaScript experience, I use dynamic element creation extensively for building responsive UI components and data-driven interfaces. The most effective method is using document.createElement() to create elements with proper attributes and content before adding them to the DOM. This approach provides full control over element properties and ensures optimal performance through efficient DOM manipulation.

Creating dynamic components allows you to switch between different components at runtime based on data or user interactions, essential for building flexible UIs like tabs, modals, or dashboards. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented dynamic component patterns in countless Vue applications over 25 years of development. From my expertise, the most effective approach is using the built-in <component> element with the is attribute to dynamically render different components. This provides clean, declarative component switching with full Vue reactivity.
