Thanks for sharing this!
If you don't mind me asking, is there a way for a non-member like me to watch/listen to these TC39 meetings without participating? Live would be awesome, but I'm also wondering if there are public recordings?
you have the agenda and additional documents here: github.com/tc39/agendas?tab=readme...
Thank you 🙏
