What is lazy loading and why is it important?

Lazy loading is a design pattern that postpones loading non-essential resources until they are needed. It's important because it improves page load times and enhances user experience.

How does lazy loading work in practice?

In practice, lazy loading works by using JavaScript to load images or other resources only when they are about to enter the viewport, reducing initial load time.

Can you give me an example of lazy loading in a website?

Sure! A common example is an image gallery where images are only loaded as the user scrolls down the page, rather than all at once.

Are there any downsides to using lazy loading?

Yes, potential downsides include SEO challenges if not implemented correctly and possible delays in loading content that users expect to see immediately.
