描述

I searched on the issue tracker and repo but didn't find anything about it, are there any plans to add a polyfill for AbortController and AbortSignal? It's primary purpose is to be able to cancel fetch requests, but can also be used manually as a standard mechanism for cancelling promises or any kind of async behavior.

The final version of AbortController has been added to the DOM specification The corresponding PR for the fetch specification is now merged. Browser bugs tracking the implementation of AbortController is available here: Firefox: #1378342, Chromium: #750599, WebKit: #174980, Edge: #13009916.

研究方向
This issue requests a polyfill for AbortController and AbortSignal in core js. The spec is at https://dom.spec.whatwg.org/#aborting ongoing activities. Look at existing polyfills in core js (e.g., 'modules/') for pattern. The corresponding fetch PR is merged, so ensure alignment with fetch spec. The polyfill should be placed in a new module and registered properly. Check comments for any additional requirements.
