There is Inline::Lua, although JS is probably more popular nowadays. In that vein, there is JavaScript::V8, JavaScript::Duktape, or even the pure-Perl JE, which is available in Debian as libje-perl.

Update:

use warnings;
use strict;
use JE;

my $j = new JE; 
$j->eval(<<'MYJSCODE');
function foo (x) {
    return x / 10;
}
MYJSCODE

my $rv = 0+$j->{foo}->(50);

print "$rv\n"; # prints "5"
