> parseDate.setMonth(++parseDate.month); > Then that statement above gives different results to: ++parseDate.month parseDate.setMonth(parseDate.month);
which gives: Sat Nov 1 00:00:00 GMT+0000 2008 Sun Feb 1 00:00:00 GMT+0000 2009 Mon Dec 1 00:00:00 GMT+0000 2008 Sun Feb 1 00:00:00 GMT+0000 2009 Thu Jan 1 00:00:00 GMT+0000 2009 Sun (i.e. it behaves as you would expect) Shouldn't the two versions be executed the same way? - i.e. month is incremented from 11 to 0 by the ++month (causing the year rollover) and then this 0 is passed into setMonth which should just set it to 0 again and cause no rollover. The call to setMonth is superfluous (though personally I'd go with setDate(parseDate.month + 1)) but shouldn't actually be doing anything as in both above cases it's just being passed 0 and so should either cause a year rollover in both cases (which would be buggy but consistent) or in neither case, that it's different is a bit worrying.
