- Improved User Experience: Faster-loading web pages provide a seamless and enjoyable experience for users.
- Better SEO Ranking: Search engines prioritize fast-loading websites, potentially boosting your SEO ranking.
- Cost Savings: Optimized code requires fewer server resources, reducing hosting costs.
2. Use Async and Defer Attributes
defer attributes. This ensures non-blocking loading, allowing the HTML parsing to proceed without waiting for script execution.
3. Optimize Images and Other Media Resources
Compress and optimize images and media resources to reduce their file size. This leads to faster page loading times.
5. Apply Code Splitting
6. Utilize Browser Caching
Set appropriate cache headers to enable browser caching. This allows returning visitors to load your site more quickly.
7. Optimize Loops and Iterations
Streamline loops and iterations. Minimize redundant calculations and reduce loop iterations for improved performance.
8. Avoid Excessive DOM Manipulations
DOM manipulations can be resource-intensive. Minimize them by batching operations and using document fragments for multiple DOM changes.
9. Implement Event Delegation
Event delegation optimizes event handling. Reduce the number of event listeners for increased efficiency.
11. Profile and Benchmark Your Code
12. Optimize Network Requests
Reduce the number of HTTP requests by optimizing API calls, implementing caching, and minimizing unnecessary requests.
13. Minimize Memory Leaks
Proper memory management is essential. Clean up unused variables and objects to prevent memory leaks.
14. Implement Server-Side Rendering (SSR)
Consider server-side rendering (SSR) to render initial page content on the server. This reduces client-side rendering load and enhances the time to first meaningful paint.
