Learn techniques to make your web applications faster and more responsive, improving the user experience.
Web performance is not a luxury; it's a core feature. Slow-loading applications lead to high bounce rates and user frustration. This topic covers critical optimization techniques. We'll start with frontend strategies like 'code splitting', which involves breaking your JavaScript bundle into smaller chunks that can be loaded on demand, and 'lazy loading' for images and components, which defers loading off-screen assets until they are needed. We'll also explore optimizing assets by compressing images and minifying CSS and JavaScript files to reduce their size. On the logic side, we'll discuss 'debouncing' and 'throttling' to control how frequently functions (like search queries or resize event handlers) are executed, preventing performance bottlenecks. Finally, we'll touch on 'memoization' as a way to cache the results of expensive function calls and return the cached result when the same inputs occur again. Tools like Google's Lighthouse and browser developer tools are essential for auditing your site's performance and identifying areas for improvement.
