I have a string that looks like "(3) New stuff" where 3 can be any number.
I would like to add or subtract to this number.

I figured out the following way:

var thenumber = string.match((/\d+/));
thenumber++;
string = string.replace(/\(\d+\)/ ,'('+ thenumber +')');

Is there a more elegant way to do it?
