Indeed. I was tracking a lot of these projects a few years ago because we had a Flex/AS3 RIA (remember that term?) so I was hoping we'd get a freebie port to HTML/JS. In the end, we ended up writing our own AS3->JavaScript transpiler[1]. The Apache Flex project has since done something similar, though by the time that was done, we were done. So my skepticism stemmed from just seeing these projects come out, get some quick wins from implementing a simple subset of swf, and then just go nowhere. But I wish them well. I hope it works out. [1]Well, not totally ours. We used the existing Falcon compiler front-end and we wrote the emitter to transpile to TypeScript (after implementing a subset of Flash SDK that we needed).
