Promisify Scroll: A Promise-Based Scrolling API Deep Dive

The provided text details a technical proposal to "promisify" web scrolling APIs, allowing methods like scrollTo and scrollIntoView to return a Promise instead of being void. This change addresses a long-standing limitation where developers had to rely on unreliable timers or event heuristics to detect when a smooth scroll animation finished. By returning a promise that resolves upon completion or interruption, the new API enables cleaner code sequencing using async/await patterns. Implementation is currently led by Google’s Blink team, with the feature being integrated into the CSSOM View specification and prototyped in Chromium. The transition is designed to be backwards-compatible, ensuring that existing websites remain functional while offering a more precise coordination for modern user interfaces. Overall, the sources highlight a shift toward more ergonomic and deterministic asynchronous patterns for browser-based animations.
