Subject Re: [FalconJx] Package down to Expression production; JSGoogEmiter prototype
Date Thu, 27 Dec 2012 16:00:06 GMT
"Full" AS to JS cross-compilation is well within our reach, apart from
E4X, which is entirely absent from all browsers except old Firefox
builds. If you look at the Wiki, I have made a table of most of the
language features of AS and indicated which solutions for the
disparities are possible. So far, when looking at JS + 'goog', I don't
see any actual show stoppers. There might be some 'nasty' workarounds
needed, but we can hide those from the user/developer ;-)

The real challenge is the frameworks on both ends (Flex SDK and
"FlexJS"). I'm leaning towards the 'long' solution, where we try to
support as much of the Flex SDK on the JS side as possible, again
using 'goog'. Having the AS - JS compilation in FalconJx 'nearly 100%'
language feature complete (and very extensible) makes it possible to
use whatever framework we want on either side.
