How to debounce a function in JavaScript
Debouncing prevents excessive function calls by delaying execution until after a specified period of inactivity. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve implemented debouncing extensively in search inputs, resize handlers, and user interaction events. From my expertise, the most effective approach is creating a closure that manages a timer, clearing previous timeouts when new calls occur. This technique dramatically improves performance by ensuring functions execute only after user activity stops.
How to Use ngDoCheck in Angular
The ngDoCheck lifecycle hook in Angular allows you to implement custom change detection logic for cases where Angular’s default change detection isn’t sufficient. As the creator of CoreUI with over 11 years of Angular development experience, I use ngDoCheck for components that need to detect changes in complex objects, arrays, or when working with immutable data structures. This hook runs on every change detection cycle, so it requires careful implementation to avoid performance issues.
How to Create Async Components in Vue
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.
How to Use useCallback in React
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.
How to Use useMemo in React
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.
How to use the key prop in React lists
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.
