What are the best practices for implementing virtual scrolling?

Virtual scrolling is a technique that allows you to render only the visible items in a list, improving performance. Best practices include using a fixed height for items, optimizing rendering with lazy loading, and handling dynamic content efficiently.

Can you explain how lazy loading works in this context?

Lazy loading means loading only the items that are currently in view, rather than all items at once. This reduces the initial load time and memory usage, as items are fetched as the user scrolls.

What libraries or frameworks support virtual scrolling?

Popular libraries include React Virtualized, Angular CDK, and Vue Virtual Scroller. These provide built-in support for virtual scrolling and help manage performance.

Are there any common pitfalls to avoid when using virtual scrolling?

Yes, common pitfalls include not accounting for item height variations, failing to handle resizing events, and not optimizing for accessibility.
