<p class=MsoNormal><span style='color:navy'>I read Virding’s paper out of
interest, and it is quite interesting, and I was playing around in my head how
to implement Javascript in Erlang, when it struck me: why? Is it that you
want to embed code written in Javascript into an Erlang program? That you
think an Erlang implementation would be faster (or better in some other way)
than existing ones? Or is it just out of intellectual curiosity?</span></p>
<p class=MsoNormal><span style='color:navy'> </span></p>
<p class=MsoNormal><span style='color:navy'>I ask because I do a lot of
Javascript programming (server-type applications, not part of any
browser). One of the things I like about Javascript, however, is its portability.
I can use the libraries I develop for my applications (say, an implementation
of a heap, or scheduler, or a parser) on a web page without any problem.
(I don’t generally program web pages, but others in my team do.)
But I would never want to compile my Javascript libraries to Erlang; it would
be much better to rewrite them.</span></p>
<p class=MsoNormal><span style='color:navy'> </span></p>
<p class=MsoNormal><span style='color:navy'>So for me the opposite would seem
to be more interesting: compiling Erlang to Javascript. So long as you’re
willing to take the performance hit… That being said, since most
Javascript development is done for the browser, concurrent programming isn’t
as big an issue for most Javascript programmers, so I know I am in the great
minority as one of the few Javascript programmers who doesn’t care about
web programming.</span></p>

Yes, I think Erlang would be a good platform to compile JavaScript to. I<br>
have been thinking about how to do a PHP implementation and arrived at<br>
the same conclusion. The main difficulties would be the large libraires <br>
and the rather crappy syntax and semantics (of PHP).<br>
