Async components in Vue.js allow you to load components on-demand, reducing initial bundle size and improving application performance. As the creator of CoreUI with over 11 years of Vue.js development experience, I use async components extensively for code splitting and lazy loading in large applications. Async components are particularly useful for routes, modals, and heavy components that aren’t needed immediately.

As the creator of CoreUI and with over 11 years of React development experience, I’ll demonstrate how to use the useCallback hook to optimize function references and component performance.

As the creator of CoreUI and with over 11 years of React development experience, I’ll show you how to effectively use the useMemo hook for performance optimization.

Using the key prop correctly in React lists is crucial for optimal performance, proper component state management, and avoiding rendering bugs during list updates. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented key props in countless React components including data tables, navigation menus, and dynamic content lists in enterprise applications. From my expertise, the most important approach is to use stable, unique identifiers from your data as key values. This method enables React’s reconciliation algorithm to efficiently track changes, preserve component state, and minimize DOM manipulations during list updates.
