ECMAScript excitement 😉

Congrats to @manishearth.bsky.social on unflagging TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉

By many metrics this new date-time API is the single biggest change to JS ever 🔥

V8 uses Boa's temporal_rs by @jason-williams.co.uk Kevin Ness & Manish 👍

ES6 was the biggest, most revolutionizing release with all those convenient array functions, IMO. Then Promises. When the pipe operator comes, those will make up the three most important updates. Temporal might be a contender to be fourth. That's my take. 😅

That's awesome, and I'll probably finally be able to use it in around 7 years, when it's also supported in Safari and FireFox, and datepicker components, form and validation libraries also support it! 😅👍

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.

Yes! Now come on WebKit, it’s allegedly somewhere in TP builds somewhere, but I haven’t been able to figure out how to enable it.
