Weex is using custom js engine (JavascriptCore) on Android. Its version is new and supports almost all ES6 features, except modules.
I think this is a good opportunity to use ES6 in js framework and remove useless polyfills. It can improve the js runtime efficiency on Android. However, we can't upgrade the js engine on iOS. For compatibility reasons, we have to use the js framework in ES5 on iOS. The packaging process may need to change too, and how to maintain version consistency is also a problem. What do you think fellows? Best regards, Hanks
