Bug ID: 241414
Summary: Add support for Atomics.waitAsync
Product: WebKit
Version: Safari Technology Preview
Hardware: All
OS: All
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: florens at fvsch.com
We at StackBlitz are using Atomics.waitAsync (https://github.com/tc39/proposal-atomics-wait-async, apparently stage 3 and shipped in Chromium) on stackblitz.com to power our Node.js-in-the-browser port (called WebContainers).
Firefox doesn't implement Atomics.waitAsync either, but we were able to implement a polyfill using workers-in-workers, something that is not possible in Safari at this time.
The lack of Atomics.waitAsync in WebKit is one of the things stopping us from offering WebContainers to users of Safari and other WebKit-based browsers at this time. (Others include bug 174931, bug 238442, and possibly more we haven't identified yet.)
