CSS vs. JavaScript

This article explores the performance differences between CSS-based and JavaScript-based animations. It challenges conventional wisdom by explaining that while both can be efficient, CSS animations run on a separate thread, making them less susceptible to main thread blocking. The article provides code examples for both approaches and includes a simulation to demonstrate how JavaScript animations can be disrupted by other processes. It covers key concepts like requestAnimationFrame, CSS keyframes, and browser rendering threads, making it a valuable resource for web developers optimizing animation performance.
