Unlucky? Adobe had us writing typesafe ECMAScript, JSX and SwiftUI in 2006.

The unlucky ones were folks who thought they had to use PureMVC, cairngorm or RobotLegs to build large applications.

Huh? How?

I'm exaggerating; Adobe Flex's MXML was an XML schema for building application UIs declaratively. It supported custom elements, which would correspond to classes you'd write, whose constructors, fields and methods would mirror the attributes and events on the DOM, kind of like a stricter HTML5.

That's a good description of the Flash ecosystem from 2006 onwards, actually: before its time, and more stringent than what came after. That strictness was the legacy of ECMAScript 4, I suppose.

MXML

Flex was built on top of Flash and gave a very nice, wildly ahead of it's time, environment for building Rich web Business Applications.
