Its not JavaScriptCore, its webkit (UIWebView which is non-Nitro).
Tab syncing is one heck of a benefit, I can't wait to switch. Now I'm definitely going to stick with Chrome on my desktop, even though I'd been considering going back to Firefox. Quite disappointing on Apple's part that its only in iOS 6 that Notes and Calendar will be synced with OS X, still not Safari tabs.
Months away. And I don’t think that’s really an argument against Chrome on iOS. Different people like to use different browsers on the desktop. If you use Chrome you don’t get tab syncing with mobile Safari. Also, some people might for example have an iPad and an Android phone. With mobile Safari, there is no way to sync tabs between the two. With Chrome there is.
Is JavaScriptCore not the WebKit JavaScript engine?
My point was that one of Chrome's main allures is V8, and if it's using stock WebKit (and therefore JavaScriptCore) there doesn't seem to be much point in using Chrome at all.
Well, both (desktop) Chrome and Safari are based on webkit, which I believe is the DOM rendering engine rather than the JS interpreter (nitro, v8, etc). Most users don't really care whats under the hood anyway, just that it works.
