How about: "ES7 will most likely have async/await when it's finished."

Sorry, using the present tense for things that will be in browsers years later (hopefully) is a common practice that's an issue with me. Let's stick with what people can actually use today.

Also, pointing to features people can use in different dialects of JavaScript is not really fair. Just about everything you can think of has been experimented with and probably deployed somewhere. It doesn't count unless it's all available in the same toolchain and can be used in a unified way while writing a single app.

ES7 async/wait is available now via the ES7 polyfill Babel.js: http://babeljs.io/

There are a ton of polyfills available right now for ES6/ES7 features: http://kangax.github.io/compat-table/es7/

BTW I also think that the current state of aggressive polyfills is also influenced by Dart's compile to JS functionality. :)

Comparing Babel.js to dart2js is fair. I'd be interested in hearing more about about how well it works in practice from people who use Babel.js for large apps. (Also, how does it compare to Typescript?)

[spellboots]

Anyone creating a new Ember.js application today is using babel by default. It works very well in my experience. I haven't used typescript however.

I think with time Typescript and Babel.js are to be merged, if you through in Strong Script to the mix I guess you have the future of JavaScript.

If that's the metric we're applying, Dart fares no better...

[spankalee]

How so? You can use Dart today and yesterday and tomorrow.

wycats: IE 10 and up, Safari 6 and up, Chrome, FF, Opera, last 2 versions.

In what browser?

[wstrange]

Chrome, Firefox, Safari and even IE!

All via dart2js

[nailer]

Sure but you can also use es7 today (which I did).

[axlprose]

Yes, and even compared to ES7, Dart still fares rather well. Most people that doubt this seem to not have actually tried the Dart workflow and core libraries. The productivity gain from those two features alone makes it compelling against all other compile-to-js options, because what it brings to the table isn't just a fancy language with nicer syntax+semantics.
