Re^4: Yet Another Rosetta Code Problem (Perl, Ruby, Python, Haskell, ...) (js)

It works just fine. Try pasting the following into your url bar:

javascript:alert("ZBBBCZZ".match(/((.)\2*)/g))

That should alert the output of .toString() called on the array result.
If you have Firefox use the following to see the unadulterated array source:

javascript:alert(("ZBBBCZZ".match(/((.)\2*)/g)).toSource())

Update: Does that imply that Javascript has different capture semantics than perl?

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. - tye	[reply] [d/l]

Telling `m//g` in list context to forget about the captures and just return the matches: `@list = "ZBBCZZ" =~ /(??{'(.)\1*'})/g;` [download] or probably more exact: there are no captures `m//` can see	[reply] [d/l] [select]
