Well, this is a V8-specific list, and Object.observe ships in current V8. ;) As for Chrome, a version with a respective V8 version is in Canary and the feature will be available in Chrome 35 (just like promises). I agree that it would be nice for announcements like this to be mirrored to the Chromium list, though. /Andreas > By the way, it would be nice to have all of the Chromium related (Blink, V8, > WebRTC and anything else that is built into Chromium) intent threads in one > place, instead of subscribing to many groups that publish intent threads. > I guess this has caused Object.observe to be excluded from the latest > Chromium blog post about Chrome 34. > > For references, here is the missing intent thread for Object.observe - > https://groups.google.com/forum/#!searchin/v8-users/subject$3Aintent|sort:date/v8-users/aeSFJK1L5n4/zvC0E-2cXWUJ > > And other V8 intent threads (mostly intents to implement. > ArrayBuffer.isView, Object.observe and this thread are the only intents to > ship) - > https://groups.google.com/forum/#!searchin/v8-users/subject$3Aintent%7Csort:date > > > ☆PhistucK > > > On Thu, Mar 20, 2014 at 11:46 AM, Jochen Eisinger <[email protected]> > wrote: >> >> FYI - V8 promises will be enabled hopefully for M35.
