Review of the nodejs code

Hello expert,

 I have a piece of code which i used it in other, is it a correct way of doing it or any other way we can have

function addZero(i) {
	if (i < 10) {
		i = "0" + i;
	}
	return i.toString();
}

Select all Open in new window

//---  create current date in YYYY-MM-DD HH:MM:SS format ---//
function curDate() {
	var d = new Date();
	var crDate = d.getFullYear()
	+ '-' + addZero(d.getMonth() + 1)
	+ '-' + addZero(d.getDate())
	+ ' ' + addZero(d.getHours())
	+ ':' + addZero(d.getMinutes())
	+ ':' + addZero(d.getSeconds());
	return crDate;
}
}
