The Fast and the Curious: Taming JavaScript’s Idle Time
Your app isn’t slow, it’s just rude! While you’re trying to scroll, it’s busy crunching data like there’s no tomorrow. In this talk, we’ll teach your JavaScript some manners.
We’ll peek under the hood of the browser’s event loop, meet the mysterious requestIdleCallback(), and learn how to make code wait its turn like a civilized citizen of the main thread. Expect smooth UIs, happy users, and a tiny scheduler that feels like React Fiber’s younger, cooler cousin.
Because performance isn’t only about doing things fast - it’s about doing them politely.
