RegExp Linear Matching is also a nice improvement to look at Particularly for lib maintainers who often receive RegExp DOS security reports, including many harmless false positives With that feature, the number of RegExp DOS is likely to decrease, reducing our burden bsky.app/profile/seba...

Linear Matching moved to stage 1 at TC39 Apparently nobody cares, but as an npm lib maintainer, you should This could greatly help reduce the number of RegExp DOS CVEs Those CVEs are often more annoying than anything because you get a lot of false positive security alerts

Await Dictionary / Promise.allKeyed() is a nice pragmatic improvement! bsky.app/profile/seba... (linking posts for my readers)
Seb ⚛️ ThisWeekInReact.com⚠️ Promise.all() makes your code sensitive to destructuring order 🆕 Promise.allKeyed() is IMHO a better alternative in many cases I've been using my "combine-promise" lib for that, and can finally deprecate it soon
The most exciting to me is Composites pursuing an interning approach! More info here: bsky.app/profile/seba...

Rob PalmerECMAScript excitement 😉 Congrats to @ashley-c.bsky.social on advancing the Composites proposal to Stage 1 at TC39 today 🎉 This is the evolution of Stage 2 Record & Tuple which has now been withdrawn. A key difference is that Composites are objects, not primitives. github.com/tc39/proposa...

Rob PalmerECMAScript excitement 😉 Congrats to my coworker @ashley-c.bsky.social at TechAtBloomberg on advancing Await Dictionary to Stage 3 at TC39 🎉 Promise.all returns positional results as an array. Promise.allKeyed allows named results inside an object 👍 github.com/tc39/proposa...
