JavaScript Infrastructure & Tooling at Bloomberg. Co-chairing TC39. Likely to tweet tech stuff about JS & software performance. Opinions are my own.
TC39 will also discuss:
🔶 Async Iterator Helpers
🔶 Class composition
🔶 Composites
🔶 Concurrency Control
🔶 Decorators
🔶 Temporal
🔶 test262
🔶 Trailing zeros in Intl.NumberFormat
🔶 WHATWG Stages
You can see the full agenda here:

Temporal_rs has been released!!!
This is the first public release of Temporal_rs, a Rust implementation of the Temporal API powering Boa, Kiesel, V8 plus other engines.
This will be shipping in Chromium soon

Temporal is estimated to land in Chrome 144 which becomes stable on 7th January 2026. This could change.
Temporal is already available in Firefox and is in development for Safari.

That's illegal.
Also, the gravy is meant to fill and overflow the yorkshire. Pre-filling with peas is acceptable but you've overstepped by putting carrots in there too.

For basic glossary access, I suspect they fetch a cached human-reviewed definitions. It's cheaper and eliminates the unpredictability risk. Some children will miss out on that due to the paywall.
For the interactive Q&A, I'm curious if it will go beyond pre-canned. Might pay to experiment.
