@bakkot:matrix.orgbakkot That said it's definitely an improvement: for consistent comparison functions, compareFn(a, b) < 0 means "put a before b, regardless of where they were originally", not "leave them in their original order" 04:28:18
@sideshowbarker:mozilla.orgsideshowbarker HE Shi-Jun: Thanks for commenting over there 06:13:32
@sideshowbarker:mozilla.orgsideshowbarker bakkot: maybe I can push a commit to that branch with trims the change down to that 06:15:14
@sideshowbarker:mozilla.orgsideshowbarker bakkot: in the meantime, a comment from over there would be welcome 06:15:56
@sideshowbarker:mozilla.orgsideshowbarkerI wish the spec itself has some more explicit language for developers on this06:16:22
@sideshowbarker:mozilla.orgsideshowbarkerI am very happy with the spec sections that now have the non-normative green notes sections with explanatory text06:17:06
@sideshowbarker:mozilla.orgsideshowbarker bakkot: thanks for adding a comment on that MDN PR 08:25:24
@sideshowbarker:mozilla.orgsideshowbarkerdoes the change in https://github.com/mdn/content/pull/7027/files seem like a reasonable way to work around the issue described in https://github.com/mdn/content/issues/7026?08:52:18
@sideshowbarker:mozilla.orgsideshowbarker hmm, I guess this isn’t specifically a JavaScript issue – so will re-ask on #whatwg:matrix.org 08:53:34
@sideshowbarker:mozilla.orgsideshowbarkerhttps://github.com/mdn/content/issues/7034 is a good first issue for anybody interested in contributing to MDN10:29:47

@sideshowbarker:mozilla.orgsideshowbarker where does the errors property of AggregateError instances come from? 06:25:27
@sideshowbarker:mozilla.orgsideshowbarkersee also https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/any#rejection06:30:20
@sideshowbarker:mozilla.orgsideshowbarker
If all of the passed-in promises reject, Promise.any asynchronously rejects with an {{JSxRef("AggregateError")}} object, which extends {{JSxRef("Error")}}, and contains an errors property with an array of rejection values.

@sideshowbarker:mozilla.orgsideshowbarker errors is not part of the prototype of AggregateError, so I don’t understand where it’s coming from 06:32:14
@sideshowbarker:mozilla.orgsideshowbarker looking at the spec at https://tc39.es/ecma262/multipage/fundamental-objects.html#sec-aggregate-error-objects, I also don’t see any mention of errors 06:35:36

https://tc39.es/ecma262/multipage/fundamental-objects.html#sec-aggregate-error Step 5

Perform ! DefinePropertyOrThrow(O, "errors", PropertyDescriptor { [[Configurable]]: true, [[Enumerable]]: false, [[Writable]]: true, [[Value]]: ! CreateArrayFromList(errorsList) }).

@sideshowbarker:mozilla.orgsideshowbarkerIf somebody has energy to add a comment over at https://github.com/mdn/content/pull/7386, I would appreciate it16:41:21
@bakkot:matrix.orgbakkot Domenic: current status is that I'm gathering feedback on usability. I need to follow up on that, so thanks for the ping. 16:44:31
@bakkot:matrix.orgbakkot(people had plausible usability concerns about async do also, which is why I'm not just going forward with it)16:45:03
@domenicdenicola:matrix.orgDomenicK, just wondering at what point we should make all web platform functions that take promises take functions that return promises as well17:05:52
