NodeJS

Good read, thanks.

On the server-side, you don’t mention NodeJS? To my mind, JavaScript is the toughest competitor to Dart — and all other languages being used for web/network services and apps.

Dart is designed to be a better JavaScript, more akin to Java. But JavaScript is evolving, via ES6, ES7/2016 and TypeScript, supporting classes, decorators and optional typing, more akin to Dart. Moreover, these new features are already available via Babel, without having to wait for native browser support.

This doesn’t bode well for Dart’s design goal. Better technologies commonly loose to the incumbent with broader support and larger eco-system.
