Michael Schmalle made it possible to create a SWC like our js.swc that contains the playerglobal.swc equivalent for the browser. It contains HTMLElement, Document, Window, XMLHTTPRequest, etc. The source for the externs comes from Google Closure Library. This allows us to write fully functional JS applications and frameworks by writing them in AS, even in an IDE with code completion, and outputting JS. The FlexJS 0.5.0 framework currently consists of thousands of lines of JS code handwritten by Peter and I and others. We are almost done rewriting those JS files in AS. The advantages are significant. The compiler catches things sooner, we don't waste time forgetting to type 'this.' or debugging when we do, we don't waste time typing out package path names, etc. Also, the AS code for the SWF and the JS code for the browser for any particular component often shared quite a bit of code and now all that shared code is in one file with conditional compiles for JS or SWF-specific code. In the end, I now strongly believe that AS is a better language for writing JS. I expect that we'll be able to create components in FlexJS much more quickly this way. -Alex
