I have this code:

var r = /(?:^s*([^s]*)s*)(?:,s*([^s]*)s*){0,}$/

var s =    a   ,  b  , c 

var m = s.match(r)

m => [   a   ,  b  , c , a, c]

Looks like the whole string has been matched, but where has b gone? I would rather expect to get:

[   a   ,  b  , c , a, b, c]

so that I can do m.shift() with a result like s.split(',') but also with whitespaces removed.

Do I have a mistake in the regexp or do I misunderstand String.prototype.match?

so finally i went with /(?=S)[^,]+?(?=s*(,|$))/g, which provides exactly what i need: all sentences split by ',' without surrounding spaces.

'       a,    OMG     abc b a b, d o WTF        foo     '.

  match( /(?=S)[^,]+?(?=s*(,|$))/g )

=> [a, OMG     abc b a b, d o WTF        foo]

many thanks!
