It's also a thorny political problem.

Remember that Dart started as an attempt to evolve web programming past some of the perceived deficiencies of JavaScript. It came out of Google, who also maintains a significant share of the web platform via Chrome. There were a bunch of snarky comments about Google trying to colonize the web and force its new language upon everyone. Fast forward a decade+: now most professional web dev is done in TypeScript, a Microsoft language that's backwards compatible with JavaScript. JavaScript itself has evolved to address some of the complaints of the past. Dart is now the VM embedded in Flutter runtime, and has sworn off ever being baked into a browser.

There are two methods that have been successful at changing the web:

- Spend countless manhours and calendar years building consensus among dozens of people through the standardization process, and hope at the end of the day that your pet proposal is one of the few that survive. There are many awesome proposals that have never made it out of committee.

or

- Build a thing that's compatible with the existing platform (e.g. React, CoffeeScript, etc.), and get a critical mass to adopt it organically, until is has the influence that the web platform will change to meet the demand.
