I didn't say dart is bad, it's way better than perl for example. The parent is the one making an outrage claim (dart is better than every other language they have tried "by a long shot"), so I think the burden of proof in on them.
It started out as a compile to js language (think coffeescript), then they created a vm for it. Google made dart so that they wouldn't have to directly compete with react native/cordova.

Are you joking? I don't have any biases for or against dart and understand why they created a new language instead of picking an existing one. But honestly, dart is not a very good language to program in.
Why do you think dart is better than these other languages "by a long margin"?
I would like to but the performance is a dealbreaker. If I'm on windows, I can expect to run latest titles at 60 fps on my 4 year old rig. That isn't possible on wine/proton.
