I'm sad every day that Dart didn't get bigger than it is. It's really a great language. Compiles to AOT too.

I know, it's underrated but it is what it is. I still continue using it.

Dart looks ok, but looking at the Dart equivalents of JS examples like {foo: 1}, I'd rather use JS

There is sadly no equivalent to {foo: 1} in Dart. This difference stems from Darts class based object model while JSs is, as you probably know, prototype based

That's my issue with this, I like the prototype system. It's very convenient for this kind of use case.
