I use Django a lot too, but JavaScript (ES6 specifically) just isn't a big mental shift anymore. I prefer Python syntax, but Python, Ruby, and JavaScript are pretty comparable at this point.

Also JavaScript has a pretty good variety of languages that compile to it. If you like C#/Scala/Swift use TypeScript. If you like Java use Dart. If you like Lisp ClojureScript.

If you come from Python or Ruby you'll probably have an easier time with Dart than with JavaScript.

Dart comes with a batteries included standard library inspired by Smalltalk (https://www.dartlang.org/docs/dart-up-and-running/ch03.html).

Dart should also feel familiar to people coming from C#. async/await support in Dart was designed by Erik Meijer (who worked on the feature for C#) and iirc he believes it is the Dart implementation is the cleanest implementation yet.

I don't see much similarity between Dart and Java.

I've done many many years Java, then hit Dart and was very impressed.

Since that I have had to do a fair bit of python, php and JavaScript at work. I think if I hadn't seen Dart first I would have quite liked python.

The problem with Dart is that once you've been developing in it for a while it spoils you from liking anything else. I really cringe with python, JS etc autocompleting to a million irrelevant things.

And going back to Java you have the slow dev loop that comes with a compiled language.

At the end of the day I've simply never had a development experience anywhere near as productive and enjoyable as Dart.

Use ES6 via http://babeljs.io/ already, and be happy :-P.

Definitely! Though, unit-testing becomes interesting, as `rewire`, `proxyquire` and other ways of changing the dependencies inside your modules when they are `import`-ed breaks.

However, it turns out having an AST of your Javascript code is really useful, and lets you do things like this: https://github.com/speedskater/babel-plugin-rewire

I also came from a Python (Django, Flask, …) background and had the same issues. Tried CoffeeScript and it helped a little but eventually fell in love with Dart.

Give it a try. I like that it comes with a useful and well designed standard library (like Python).

Thanks. I did try Dart and our team spent a full month giving it our best for our client.

It was a dream to use compared to JS. One show-stopper though: browser support. At the time, IE11 was just released and Dart had issues with IE11. Also, the Dart supported browser window is only the latest 2 versions of a given browser.

This totally killed our Dart prospects, as our target users in our business are generally non-tech savvy and we need to support older browsers like IE8/IE9.

I hope we all will be able to target evergreen browsers sooner rather than later. Microsoft seems to go into the right direction at least.
