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.
