That&#x27;s awesome! With SpiderMonkey hitting 90%, WebKit at 81%, V8 92% and Chakra at 80%, ES6 as production target becomes realistic!<p>I&#x27;m wondering when Android&#x2F;iOS default browsers will get updates because that&#x27;s going to be the one remaining blocker. (and IE11 of course... but that&#x27;s just waiting for userbase to move away from it :&#x2F;)
