What are some effective tools for testing lazy loading in web applications?
There are several tools you can use to test lazy loading, such as Google Lighthouse, WebPageTest, and GTmetrix. These tools help analyze loading performance.

Are there any browser extensions that can help with this?
Yes, there are browser extensions like 'Lighthouse' for Chrome and 'Web Vitals' that can help you monitor lazy loading and overall performance.
How can I implement lazy loading in my web app?
