I had an application a few months ago where I wanted to use JS in a Perl script to re-sort a short list in a cgi form without requiring a round trip to the server. I needed to have the Perl script write the code to fill the JS array. Being somewhat new to both Perl and JS, I had much difficulty finding examples of how to do this, and felt there should have been much more in Supersearch about writing JS with Perl.
You may be using one language to generate code for the other, or maybe you found a way to use both languages together, but with normal CGI programming, you have strict separation of client and server side.
You needed some Perl to fill a JS array. Surprise: that has nothing to do with JS, only with its syntax. You would probably want to generate JS, which is (from Perl's view) just a string of code:
my @foo = qw(foo bar baz);
my $js = 'foo = new Array(' . join(', ', map "'\Q$_\E'", @foo) . ');';
Or something like that.
That is HTTP, HTML, CGI and server maintenance related. It is NOT Perl related! CGI can be written in any programming language that can handle environment variables and stdin/stdout. Yes, you can write CGI programs in C, GW-Basic, Pascal, Visual Basic or even Brainfuck if you don't care about the environment variables.
