Just crop the string:
var date = new Date("2013-03-10T02:00:00Z");
date.toISOString().substring(0, 10);
Or if you need only date out of string.
var strDate = "2013-03-10T02:00:00Z";
strDate.substring(0, 10);

Try this
date = new Date('2013-03-10T02:00:00Z');
date.getFullYear()+'-' + (date.getMonth()+1) + '-'+date.getDate();//prints expected format.
Update:-
As pointed out in comments, I am updating the answer to print leading zeros for date and month if needed.
date = new Date('2013-08-03T02:00:00Z');
year = date.getFullYear();
month = date.getMonth()+1;
dt = date.getDate();
if (dt < 10) {
dt = '0' + dt;
}
if (month < 10) {
month = '0' + month;
}
console.log(year+'-' + month + '-'+dt);Videos

That said, we technically allow two numeric formats here. ... The former is much more common though. The separators are critical here, that's how we avoid confusion.
