probably because there are so many js “frameworks” that they are running out names
If there was one time when we could have escaped the client side hell that is JavaScript it would have been then, when chrome had astonishing market share, and Dart could compile down to JS to ease the transition until native support became standardized.
But nope, here we are with anotherone.js every week.
I think we're very lucky that Chrome never decided to include that Dart VM. Typescript turned out to be much better than Dart.
I think we can agree to disagree. I would much rather use Dart, imo.
Case in point: Angular has an alternative Dart implementation which is AFAIK used by Google internally, but it didn't take the web by storm and currently the TS flavour is by far the dominant one.
