Tests your grasp of UI virtualization in Compose. Answer: Use `LazyColumn` as it only composes visible items. Contrast this with `Column`, which composes all items at once, causing poor performance. Mention the `items` DSL.

This tests your understanding of UI virtualization and performance optimization in Jetpack Compose. A great answer identifies `LazyColumn` for large lists, explaining it only composes visible items, unlike a `Column` which composes everything at once, causing massive performance degradation with hundreds of items. Mention the `items` DSL within `LazyListScope`. A major red flag is suggesting a `Column` with a `verticalScroll` modifier, as this offers no performance benefit and misses the entire point of virtualization.
