The text discusses the challenges and solutions related to scroll-linked animations on web pages, emphasizing the inefficiencies and usability issues that can arise from improper implementation. To address these problems, it highlights two main approaches: using JavaScript and CSS. JavaScript solutions involve employing the IntersectionObserver API to efficiently handle discrete scrolling events without relying on expensive scroll event listeners. The newer IntersectionObserver V2 introduces visibility tracking, although it may impact performance. For continuous scrolling effects, the text suggests debouncing and throttling methods to manage event handler execution rates. It also advocates for CSS substitutions, which leverage browser optimizations to improve performance and user experience. The document underscores the importance of using CSS properties for scroll-linked animations when feasible and encourages proper optimization techniques in JavaScript for scenarios where CSS is insufficient.
