Ash mentioned Java2Script in the thread of “Java-JavaScript Compiler” in GWT’s group forum. And I joined in the discussion. I was not intended to post another GWT v.s. JavaScript post there (But it seems it was a v.s. thing actually). I just wanted to share things, correct my understanding and learn new things.
In those discussion, Bruce from Google told us that GWT’s motivation is “to be as small and as efficient as possible” and its two separate goals are:
(1) Create highly optimized JS output
(2) Optionally, publish selected parts of your code with a JS-compatible API
I thought that wais a very clever design. And I admired GWT team for its “excellent 100k ~ 200k final *.js files with very good performance”.
OK, if you are interested in Java to JavaScript technology, just go to GWT’s forum and ask GWT team for more details.
By the way, it seems that Java2Script website provides no detailed documents about Java to JavaScript compiler technology. I posted some details there in the discussion. Just check it out there. Or you can check sources from SVN for more details.
