What are the differences between native lazy loading and JavaScript lazy loading?

Native lazy loading is a browser feature that allows images and iframes to load only when they are in the viewport, while JavaScript lazy loading involves using scripts to achieve similar functionality, often with more customization.

Are there any compatibility issues with native lazy loading?

Can I use both methods together?

Yes, you can use both methods together. For example, you can implement native lazy loading for supported browsers and fallback to JavaScript for those that don't support it.
