words' regex argument crashes with quantifiers

[ejoubaud]

As soon as I add a quantifier in words' pattern argument, I get an error I wouldn't with the original JS method split:

var a = _('1 2,  3').words(/, +/);
// => SyntaxError: Invalid regular expression: /^, ++|, ++$/: Nothing to repeat
var b = _('1 2,  3').words(/, */);
// => SyntaxError: Invalid regular expression: /^, *+|, *+$/: Nothing to repeat
var c = _.words('1 2,  3', /, */)
// => SyntaxError: Invalid regular expression: /^, *+|, *+$/: Nothing to repeat

Unrelated: Why use the obscure name words instead of the basic JS/Ruby well-known split ? I'd strongly +1 an alias.

Apart from that awesome job with this lib guys, thank you very much.

I have same problem:

var array = s.words(" A01 ,  'B02' ;  'C03' ", /\W+/); 
// throws SyntaxError: Invalid regular expression: /^W++|W++$/: Nothing to repeat

I fixed it with following code: (is not general fix, but give an idea on how should be fixed)

if (isBlank(str)) return [];
return = trim(str, /\W/).split(/\W+/);

• As trim adds the quantifiers automatically (+) then delimiter parameter should avoid it
• To get the expected result, on the split call have to be added the + quantifier.
