2026-04-01 [06:50:07.0012] 🎉 The import-text changes were just merged into the [HTML Standard](https://html.spec.whatwg.org/#:~:text=If%20moduleType%20is%20%22text%22%2C%20then%20set%20moduleScript%20to%20the%20result%20of%20creating%20a%20text%20module%20script%20given%20sourceText%20and%20settingsObject.). [06:57:21.0355] That does mean that HTML currently has a normative dependency on the TC39 Stage 3 [import-text proposal](https://github.com/tc39/proposal-import-text), but apparently this is normal and not novel. [07:55:10.0381] the ECMA-402 2026 release candidate is out as well: https://tc39.es/ecma402/2026/ [08:08:20.0817] * the ECMA-402 2026 release candidate is out as well: https://github.com/tc39/Reflector/issues/531 [09:56:04.0501] Looking for a bit of help with spec-text drafting https://github.com/tc39/proposal-thenable-curtailment/issues/11 2026-04-03 [18:52:19.0068] @pchimento:igalia.com At the last plenary, you asked for a roadmap of the iterator built-ins. I put together this roadmap based on in-progress proposals and what's currently on my radar: https://gist.github.com/michaelficarra/34c47e1161b9ba2526ee197e1f5cb624 [19:14:19.0395] I also want a `.withCleanup` method for attaching behavior to `.return` [08:06:25.0829] @bakkot:matrix.org shouldn't you be working on async iterator helpers? 😜 [08:43:04.0828] thanks! [08:46:19.0208] (I definitely want takeWhile/dropWhile, FWIW) [11:53:27.0760] yes yes that is my first priority 2026-04-06 [12:21:06.0743] what's our LLM policy again? https://github.com/tc39/ecma262/issues/3800 [12:36:51.0772] https://github.com/tc39/how-we-work/blob/main/AI_POLICY.md 2026-04-07 [13:12:08.0018] hey aki and chairs - the notes aren't in the doc anymore, and there's no PR yet. any update? [13:12:38.0890] * hey Aki and chairs - the notes aren't in the doc anymore, and there's no PR yet. any update? [13:13:23.0585] can i help you https://github.com/tc39/notes/pull/404 [13:13:40.0070] you literally asked while I was clicking the button to make the PR 😄 [13:14:15.0583] Apologies, the timing of TC39 with the ExeCom and kicking off TC57 has me a little under water [16:52:41.0301] lol thanks, no worries 2026-04-08 [08:39:00.0932] What are the next steps on bringing `structuredClone` into the language? https://github.com/tc39/ecma262/issues/2555 Should it just be a needs-consensus PR? Was anyone planning on working on it? /cc @syg:mozilla.org [09:41:36.0098] i'm not planning to work on it. next steps IIRC was to satisfy Mark's Proxy requirements [09:41:40.0466] i don't recall the details [12:23:42.0304] basically just add a branch for proxies which uses the standard MOP operations just as if they were ordinary objects [12:23:53.0826] pretty trivial to spec, I can write it up if you want [12:24:07.0763] but I have basically given up on trying to get WHATWG to do things [12:24:17.0928] maybe I gotta start going to whatnot meetings or something [12:25:55.0497] alternatively we could in principle change the definition while pulling it in, which might be easier procedurally [13:05:38.0337] 🙏 @bakkot:matrix.org yes please get `structuredClone` over the finish line [13:13:07.0455] writing the spec is not actually the hard part [13:33:33.0355] here: https://github.com/whatwg/html/pull/12348 [13:55:19.0272] writing the spec is almost never the hard part 2026-04-10 [09:42:53.0116] 📢 All, please see the following Reflector issues regarding meeting planning for 2027: - Call for hosts: https://github.com/tc39/Reflector/issues/583 - Constraints survey: https://github.com/tc39/Reflector/issues/581 - Feedback survey: https://github.com/tc39/Reflector/issues/582
