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

👀 JS Composites proposal update "After benchmarking and general reflection, the proposal is now pursuing an interning based approach." - @acutmore We didn't get Records & Tuples but we may still get interned data structures in JS! Really exciting update if this lands in JS

ECMAScript 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the Composites proposal to Stage 1 at TC39 today 🎉 This is the evolution of Stage 2 Record & Tuple which has now been withdrawn.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...

⚠️ 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

ECMAScript 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...

const { shape, color, mass, } = await Promise.allKeyed({ shape: getShape(), color: getColor(), mass: getMass(), });
