Chrome Interaction Systems: Scrolling, Animations, and Input

The source material provides a detailed examination of Chrome’s architecture and how it manages user interactions like scrolling, animations, and input handling to ensure web pages feel smooth and responsive. It explains that the browser utilizes a multi-stage rendering pipeline and relies heavily on a separate compositor thread to perform dynamic updates in parallel with the main thread, thereby avoiding performance bottlenecks or "jank" caused CC by JavaScript or layout calculations. Specifically, the document discusses how scrolling and certain efficient animations (such as changes to transform and opacity) are handled off the main thread to maintain a high framerate. Furthermore, it covers input event coordination, emphasizing ntechniques like passive event listeners that allow the compositors to proceed with scrolling immediately without waiting for the main thread to check if a script will cancel the action.
