So any other languages for Firefox OS except JavaScript? Possible if
not desireable?
From a JavaScript engine point of view, I will say that most of these
languages are trying to emulate behaviors which are not well mapped to
JavaScript. I did not investigate any of the one that you mentioned above.
As example, I can briefly talk about GWT which is generating JavaScript out
of Java. The example I have in mind, is a Vector initialization in Java.
The way it got translated by GWT from Java to JavaScript had a poor
initialization sequence in SpiderMonkey which cause the object to be heavier
in memory and slower in terms of manipulation.
Not all paradigm are mapping well to the optimizable parts of JavaScript.
Emscripten is an interesting cross-compiler because it managed to target a
subset of JavaScript which appears to be an *highly* optimizable part of
JavaScript.
