I guess you all heard that
for Action Script 3 (AS3) which is a version of ECMAScript 3rd Edition.
course very good news. However a lot of people seem to think that this
will improve their DHTML applications by a factor 10 as well. This is of course not the
main bottle necks in an application today is COM/XPCOM, DOM and reflows.
Another misunderstanding on a lot of blogs is that AS3 is an
case. AS3 has a lot of features that are in the working drafts of JS2
but it also misses a lot of things that JS1.7 already supports.
This is of course not a linear relation but you get the point. If you remove the class and type system then AS3 and JScript.NET are less similar to JS2 than JS1.5.
