> Adding 0 to the variable makes Perl explicitly convert the string to a number:

However there is still confusion with some number formats like hexadecimal, because Perl only converts strings which represent integers or floats as decimals! (see perlnumber).

just run 

$a="0x10"; 
++$a;

and in Perl $a is now 1 in JS it's 17!

Cheers Rolf

UPDATE: OTOH JS obviously can't handle octals the same way:

repl> $a=010; ++$a
9
repl> $a="010"; ++$a
11
