What are the best practices for frontend optimization?

Frontend optimization involves techniques to improve the performance of web applications. Key practices include minimizing HTTP requests, optimizing images, using lazy loading, and leveraging browser caching.

Can you explain how lazy loading works?

Lazy loading is a design pattern that postpones the loading of non-essential resources at the point the page is initially loaded. Instead, these resources are loaded only when they are needed, such as when they come into the viewport.

What tools can I use to analyze my frontend performance?

You can use tools like Google Lighthouse, WebPageTest, and GTmetrix to analyze and measure your frontend performance.

How can I optimize images for the web?

To optimize images, you can use formats like WebP, compress images without losing quality, and ensure they are appropriately sized for different devices.
