I'm trying to sort an array of objects by their date property using Async.sortBy, from most recent to oldest. A bit of googleing suggests that I reverse sort order by passing obj.date * -1 in the callback instead of obj.date, but this does not have the intended effect. Obviously because the result of that is just NaN.
My dates are in the form 2012-07-12 using today's date as an example.
Sorry fr the brevity and lack of code samples, I'm on the road on my iPad at the moment.
I could just reverse the output array of the sorting I guess but that's not a particularly nice solution.
[{title: "title", date: "2012-07-12"}, {title: "title2", date: "2011-07-12"}]
what about this solution?
async.sortBy([{title: "title", date: "2012-07-12"}, {title: "title2", date: "2011-07-12"}], function(myObject, callback){
return parseInt( myObject.date.split( '-' ).join(''), 10 ) * -1;
}, function(err, results){ ... });
in converts the date string into a sortable integer and reverses it by multipling with -1.
