Angular CDK Virtual Scroll
Angular CDK Virtual Scroll is a component from the Angular Component Development Kit (CDK) that enables efficient rendering of large lists by only rendering the items currently visible in the viewport. It dynamically adds and removes DOM elements as the user scrolls, significantly improving performance and reducing memory usage for applications with extensive datasets. This is particularly useful for data-heavy applications like dashboards, tables, or feeds where traditional rendering would cause lag.
Developers should use Angular CDK Virtual Scroll when building Angular applications that need to display large lists or grids, as it prevents performance bottlenecks by minimizing DOM manipulation. It's essential for scenarios like real-time data feeds, financial applications with thousands of rows, or social media timelines where smooth scrolling is critical. Learning this helps optimize user experience in data-intensive Angular projects, making it a key skill for front-end developers working on scalable web apps.
