Question

I have two dates:

var first = '21-11-2012';
var second = '03-11-2012';

What is the best way to format it like this:

var first = '2012-11-21';
var second = '2012-11-03';

Should I use jQuery or simply JavaScript?

Answer 1

You don’t need jQuery for this, simply use JavaScript like so:

function formatDate(d){
    return d.split('-').reverse().join('-');
}

Although if you want more reusable code consider using the JavaScript Date Object.
