Angular Virtual Scroll Explained in 3 Minutes

Angular Virtual Scrolling explained with a practical Angular CDK example.

In this video, you’ll learn why large Angular lists become slow, how virtual scrolling keeps the DOM small, and how to use `cdk-virtual-scroll-viewport` with `*cdkVirtualFor`.

We cover:
- Why normal lists with thousands of rows hurt performance
- Installing `@angular/cdk`
- Importing `ScrollingModule`
- Building a virtual scroll viewport
- Setting `itemSize` correctly
- Using `trackBy` for stable identity
- Lazy loading more data near the end of the list
- Common virtual scroll mistakes to avoid

Virtual scrolling is useful when your app needs to display large datasets such as user lists, logs, tables, search results, dashboards, admin panels, or infinite feeds. Instead of rendering every item at once, Angular CDK renders only the rows near the viewport while preserving the full scroll height.

Example topics in the video:
`@for`, `*cdkVirtualFor`, `cdk-virtual-scroll-viewport`, `itemSize`, `trackBy`, `ScrollingModule`, lazy loading, DOM performance, Angular CDK.

If you build Angular apps with large lists, this is one of the simplest performance wins you can add.
