in thread Yet Another Rosetta Code Problem (Perl, Ruby, Python, Haskell, ...)
Does that imply that Javascript has different capture semantics than perl?
No. It is just that match() returns the matched substrings, not the captured substrings. If //g in a list context could be told to return the matched substrings (what it does when there are no capturing parens), then the same solution would work in Perl.
A better JavaScript solution is actually: "ZBBBCZZ".match(/(.)\1*/g). No need for the second set of parens.
