如何提高前端应用的性能？
Here are several key strategies to improve frontend application performance (within 500 words):

1. Code Optimization:
- Minify and bundle JavaScript/CSS files using tools like Webpack or Rollup
- Implement code splitting to load only necessary components
- Remove unused code and dependencies (tree shaking)
- Use modern ES6+ features for cleaner, more efficient code

2. Asset Optimization:
- Compress images (WebP format) and lazy load them
- Use SVG icons instead of font icons when possible
- Implement responsive images with srcset
- Utilize CDNs for static assets

3. Rendering Performance:
- Virtualize long lists (react-window, react-virtualized)
- Avoid unnecessary re-renders with React.memo/PureComponent
- Use CSS transforms/opacity for animations (GPU accelerated)
- Implement skeleton screens for perceived performance

4. Network Optimization:
- Enable HTTP/2 and gzip/Brotli compression
- Preload critical resources with <link rel="preload">
- Implement service workers
