1. Code Splitting

• What it does: Breaks your code into smaller bundles to load only what's necessary.

• How to implement: Use tools like Webpack, Rollup, or native features in frameworks like React's React.lazy and Suspense.

• Example:

  
  const LazyComponent = React.lazy(() => import('./Component'));
  
  

2. Minification and Compression

• Minify CSS, JavaScript, and HTML: Tools like Terser or UglifyJS can reduce file sizes.
• Gzip/Brotli Compression: Configure your server (e.g., Nginx) to compress files before sending them to the client.

3. Optimize Images

• Use modern formats: Convert images to WebP or AVIF for smaller file sizes.

• Lazy Loading: Load images only when they appear in the viewport.
